???? I noticed an improvement after accepting trims from Autotune. The map was not as good as the tune that was specific to my bike with my mods.

Recently was told by a very experienced track rider that he does not bother to install a PC on his ZX-10. NOt necessary and I'm sure he does go for performance as much as the next guy.

Hub if jeffo has a big enough library he must be street tweakin,lean it out lower to middle rpm .Every map I've had operator says rich up top,now if we had a dyno and a wind tunnel........We'd be rich

Jeffo your a Bloody Amazing! Your Map Rocks!Fantasticly Amazing Jeffo! From this

Jeffo ! Cheers Mate You ROCK!
Yesterday my Son & I put Jeffos Custom Map on her,I new straight away she was running better & "Cooler",WOW Jeffo ! You Bloody Ripper! Goody took her out down a Country Back Road he said I only opened her up 3/4 throttle Hell!Shes A Hole New Beast Mate !in third gear I overtook a car @ 3/4 throttle Man O Man she is so responsive, She nearly Ripped my arms off!anyway I passed this car looked in my mirror & the car was out of sight, Wow a Totally Differant Machine Mate the "Pull" from 3500rpm on, he said with Now the Cat gone With Jeffos MAP !The Temp Wow she stayed on 1 Bar ( it's a mild 16c today) To finish off Goody said he would really luv to know how much More RWHP Shes got Now ?

Guess What? Me Too!

How close is that pattern or far away from OEM are the X to Y's?

Exactly, how far. When all of a sudden you see #'s that are Minus 30 points down from OEM you must air on the side of Caution. I know Kawi may run it rich up top to keep her cool and alive for many years to come but Kawi was not that far off the middle.

Hub get your self a pig. ROFL.

Look, I know most of you are a bunch of plug a players.

I like that one, can I use it ? I will admit, I was that guy shhhhh. Now, One or two up from what feels Grrrreeeeeaaaat.

Some can bang on Jeff all you want but in the end there seems to be more satisfied than mot satisfied. His may not be the best map out there but at least he has been the only one to ask where do you like to play at and set it up that way. Yes our local tune shop did a map on the dyno and got 5 more hp out of it with it all being on top.

I put Jeffo's map back in because there was more where I like to play at. I have not tried an Ivans or Brocks map because I cannot afford them just to play compare. I have to send Jeff an email asking if he needs to change anything since the Leo Vince went on.

RidgeRacer has the goods. That working window is a different animal and again, some, if not most, I may be wrong, but that setup is for the tinkerers like what I am looking for. That means I get my points and advancer back like the old days.

I hear Jeffo tuned 1bads turbo 14 over the phone....say it ain't so!

What's the point of investing in an expensive dyno and tuning link software if you just need a cell phone. Heck, why not tune by braille....just sayin?

Just a hypothetical question...food for thought. If racing teams spend big bucks on dyno time and exhaust gas analyzers, why not just blow all that all off and hire Jeffo to tune over the phone? In these tough economic times it would make a lot of sense. Why are the factories not beating a path to Jeffo's door? If he's really on to something you'd think the word would have gotten out by now and Jeffo wouldn't have
To peddle his tunes over the net for $50 a pop.

Another question, all you guys are basically on the same bike, same map. Only two were different, me and Monster's bikes. Monster's shot 3 foot flames and then crapped out the plugs, my CBR got hot and lost power. Has anyone tried Jeffo's map on something other than a 14? Just sayin, maybe he dyno'd a 14 and has a decent baseline map but anything else is a crapshoot. I'm afraid someone is going to get a lean map and turn their motor into a crispy critter.

He'd better have a good baseline map... the guy has made enough $cash$, off of this forum alone, to buy himself a CT dual system and get Brocks map support along with it... just sayin'.

How much $cash$ have you made from this forum, BG? No need to answer... again... just sayin'.

I'll go lock myself in the Dog House of Solitude now.

Kruz I'm Truly Sadened that didn't go right for ya ! but Hell my ZX14 has gone from a "Beast" to a "PREDITOR" Now ! & ya mentioned

Read David's 'P.S.'

Aw geez....What's with some of youse guys?A guy gets a Jeffo map...his bike runs better than before...maybe WAY better...and some of ya just say "It can't be"...WTF?WHO cares how he's doin it?Apparently,all the guys with good running Jeffo maps are....hallucinating.(including me).I want to know.....does anyone here KNOW what the air/fuel FACTORY values are?Show me.I'm all ears.ZERO's tell you NOTHING except that no fuel is being removed or added.That's all.It doesn't show you how much is going in.Only that there is a "no change from factory" situation.

I've heard here about the "lean" condition "right where we ride"...okay...where is that?So the map shows a negative value for a certain area....but in reality....IS IT ACTUALLY LEAN?What is it being compared to...the higher values further on up the rpm scale?Every cell # change...if by one digit only,is 2%.Seeing a negative 8 or whatever LOOKS like a lean condition....but really,it's showing the percentage of fuel being removed from a what?A factory preset mix.Anyone know what that "preset" is?That's the thing here.PERHAPS Jeffo KNOWS what those factory values REALLY are.And when the guys see these maps...they're assuming that those are lean values.Maybe in reality,they aren't...not anything that would cause damage.

I've got 44,000 miles on my Jeffo map.Something like that.Anyone looking at it would warn me probably to "watch riding in that rpm range".I ride in anywhere from slow,mild cruise mode to 5,6,7 and up cruise mode.My plugs look perfect(I'm on my second set in 46,000 miles).My valves look fine...spec'd fine.My bike does not heat up excessively.It pulls great.It shifts great.If there is any engine damage....when is it gonna show up?IDK....everyone has a right natch to their opinion...it's cool...I'm just curious why there are several who feel Jeffo's maps are a crapshoot and an engine blow just waiting to happen.

He's not claiming to be the "god of the mapping world",so why are so many STILL critcizing his ability to do what he does?And who on here can say..."he's not dynoing"....who says he's not?Right there where he lives,he's got access to several Dyno machines.Anyone here KNOW how long he was Dynoing bikes BEFORE he began mapping sportbikes?Some guys have a gift to ride.Some guys,a gift to figure out how to shred on an electric guitar.Who's to say Jeffo isn't gifted at being able to put together a good map for a particular bike,and get it really good?Maybe he understands basic principles more than the average "Dyno Guy".Maybe he comprehends mixes better than some.Maybe he just has a feel for what makes what work best for X or Y engine layout.My bike runs REALLY well.And has since installing my map from Jeffo.It runs better than any Dynojet/Muzzy map.I'm guessing Muzzy,Brock,and the others have a pretty "same" type of map for a particular bike.If you ran a Muzzy,then installed a Brock for the same mods and all...I think your mapping is gonna look quite close.These guys are doing it a certain tried and true way.Doesn't mean someone else can't come along and have a different view...and different results.

Actually,nobody here KNOWS Jeffo...what he's been doing from "day one" to now.He might have been tuning bikes since he was 6 years old.Who knows?I don't.But apparently he's got quite a lot of people who know him in Nevada,or wherever that is he's working out of.

This has intrigued me from the beginning about the "JeffoMaps" thing.There does seem to be a certain amount of "can't be done" here.A good amount of it.And WHY is that?That's what I'm curious about.Maybe I'm just "not getting it"....could be.Been wrong before.

I don't remember seeing any negative values in the -30 range at all.Nothing even close.

And I'm not "pro-Jeffo" either.If his map wasn't working for me,I'd say so.

What about David's P.S?

NIce Dogo.The big values are NOT going to be possible.You can't have 4500 rpms with a ZERO throttle position.That's what I meant about some of his "values" in there.I think guys are looking at those things and thinking that's a massive fuel change(or removal).It's not.That area there won't ever be affected.You will never get a 100% throttle position at 3500 rpms.It will be passing through those rpms so quickly,you won't even know what's happening at 100%.NOBODY rides like that.The throttle % is always changing.UNLESS...you keep er right at a certain rpm for however long.But I think without going back into mine...the midrange is probably kinda similar to that posted map there.Most of my cruising is at 3500,4000,5000.And I don't do that "forever".

* Last updated by: blue07 on 7/17/2011 @ 1:14 PM *

Those #'s are the differences between the maps. Not the actual adjustment #'s... And from what I was told, the Jeffo map has already had fuel ADDED to the midrange of what was originally sent. ... Good fuel economy and "crisp" response?... U betcha!

"from what I was told"....ummmmm...."fuel added to the midrange of what was originally sent"....?????IDK....What does that mean.Those fuel values in your midrange are NOT reliable?

IDK about anyone else,but I downshift into the torque curve when I go to pass or whatever.Whatever that means for RPMs and throttle.I don't have any bog,lag or anything else.I don't try to accelerate(hammer that is) from 60 mph in 6th to 100.

I have...but I don't make a habit out of it.I do know my frontend gets VERY light whenever I downshift and accelerate hard...like when passing a line of cars going uphill.She's got plenty of pep.I'll say I rarely open er all the way up while doing that...if ever.Close maybe...but not twisting wide open all at once.I know she'll loft(even if a inch or so only).I don't want that to happen while lining up for a pass.

I don't try to loft very often...but I'm pretty sure in the right hands,she'd be up and at em at will.I haven't even approached to potential of my bike.I know that.I don't intend to either.

"from what I was told"....ummmmm...."fuel added to the midrange of what was originally sent"....?????IDK....What does that mean.Those fuel values in your midrange are NOT reliable?

Those are not the actual fuel trim values... they are the differences between the two maps being compared.
The Jeffo map is not the original map sent to the forum member. It has had fuel added to the midrange. The original Jeffo map was even more lean in the midrange (aka cruising) rpms. I do not have a copy of the map originally sent.

* Last updated by: DogoZX on 7/17/2011 @ 2:15 PM *

IDK...I think Jeffo has a formula for setting up his 14 maps.You tell him your parameters and such,he designs it for those results.IDK.Mine runs REALLY good.I tried several other maps from different people....none of em matched his performance.Just sayin you know.I'm not gonna plop down 300 dollars for a Dyno Run just to see what's actually goin on.I haven't experienced any negative engine issues that I can tell.My mechanic says everything(valves and plugs and such) are in excellent condition.At 46,000 miles....he's amazed at how good of condition my bike is(internally and on the outside as well).

That Jeffo map's been in there at least 3 riding seasons.With no change to anything in it.

I mean...to me...his approach makes perfect sense.An inline four is an inline four.Suzuki,Kawasaki,Yamaha...whatever.They all operate virtually the same.It doesn't surprise me that he could have some deeper(?)understanding of fuel mixes and such.If this is his life,why couldn't he have a certain ability to see outside the box and create maps that work well.IDK....I'm very happy with mine.

As far as him "being asked to tune the Race bikes" comment...who knows?He's got quite a following where he's at.Probably doing VERY WELL.God Bless him!

I DO know..his customer service is second to none.He's willing to answer every question you can throw at him without acting like yer askin too much.He's pretty amazing really when ya look at the big picture of what he's doing...probably for THOUSANDS of guys with bikes.

* Last updated by: blue07 on 7/17/2011 @ 2:41 PM *

I gotcha, Blue... and I get that most of Jeffo's customers are VERY happy with their maps... I'd just REALLY love to see the AFR line... I'm curious as to just how lean he is taking you.

Ya...me too...kinda.Just to see it right there.But everything seems fine so far.She runs cool(er) than with the stock mapping.Strong...smooth.Ya....My a/f readings are gonna be different than someone's at sea level....that's for sure.

You know...I called him a while back and told him I wanted to reinstall my stock pipes.Naturally,he said "what the heck for?".Ya...anyway....he tells me"you call me and let me know how that performance turns out with yer pipes back on there"...ya..."okay" I told him.A couple of weeks went by...I get this phone call in the afternoon.It's him asking me about my results.NOBODY does that that I've ever dealt with.He remembered who I was and what he did on my mapping.I told him all was cool again,I reinstalled my TiForces.He was happy about that!(for my sake anyway).Pretty cool guy if ya ask me.Asked how she was runnin,if I wanted anything different done...I told him "nah....she's good to go".

I curious to know HOW people come to the conclusion that he HASN'T been asked by some of the bigger fish to tune for em.Sometimes...you like being where yer at....I doubt if he was workin for Brocks or Muzzy or anyone else like that that he'd be calling ME up to see how things are going.Brocks couldn't give me the time of day concerning a piping question I had.Just too "little" I guess I am."He" certainly had no problem sending me e-mails about his "latest" specials though

For what it's worth....I HAVE to make my bike backfire.It won't do it unless I purposely create the situation with my downshift and throttle application.Very rare that my bike backfires,in any gear/rpm combo.It just isn't prone to doing that with this map.

.I'm not gonna plop down 300 dollars for a Dyno Run just to see what's actually goin on.

That's what I said blue,,,,, So I bought a gauge,,,, just 4 me,,, So I could see. No more Bs,, Cheaper than a Dyno run.

If we only had a map compare from monsters map ????? You can be sure things went wrong in the middle. What is your map - 20,,,, Betcha his was -30 or more.... I will do a map compare and post it if Monster will send it to me,,,,, Just a offer. A video camera on a meter would be sweet. I do not have a cam so I'm out. Great convo though, always lots to learn. Cheers.

So the gauge does what?...it connects to the midpipe there and on up to the dial?I'd need to get a bung for it on there?
