CAI + Tunning

yea i kno evo's cars a fast but i have heard that their customer service blows... i plan on getting the JLT intake and a tune this summer and then upgrading my heat exchanger then getting a pulley and idler... but i gotta do some research on tunes....

yah i had horrible service from Evo to the point i canceled my order and went to JDM

Yeah when I went to get my CAI for the V6 it took a while from Fred to acknowledge me, I was stending there for like 20 just to say what I wanted to get, he didin't even get the calibrtion code or asked if I had any other mods when loading up my tune. I just like the fact I could go there and get my stuff and they installed it for me too..

X2 I would probably have them tune my car if they were closer for me to trailor it to.

Another one to think about.... I have not used him but have heard AMAZING feedback about him. Woodbine Motorsports in MT Airy...

I use JJ at Woodbine. He really knows his stuff.

is that JJ from JJSVT?

I have a all out race tune that is pig rich that will make you smell like gas if you drive it on the street, however it made 698rwhp @17lbs. The street tune is 612 at 15lbs, but is a perfect 12:1, and I dont stink after driving it... well not like gas

I reinstall my tune at times, but I dont get it tuned unless I change something that needs a tune for..

does the ecm 4-get?mys/c came with a program from frpp.but when it was d/L it came in at 486 @ 10 psi.so the shop i went to pulled it back cause they said 430-440 is bout all these stock bottom ends could handle safely.so they pulled back as much as they could to just over 460.just never heard of havin toreinstall a tune.
sorry bout jackin da thread dude,i'll stop

JJ is "Joseph Jones" from Woodbine Motorsports up in Carroll County. He doesn't provide mail order tunes but has spent many years tuning Ford Lightnings and late model Mustangs (although he does occasionally tune first and second gen cars). He's nationally recognized in the Lightning community, and even JPC in Glen Burnie sends folks his way for custom tunes.

Regarding the need to "refresh" tunes, the S197 processor has software that adjusts to driving style (adaptive programming), and this is ESPECIALLY true on the automatics. Manual transmissions have less a chance of "drifting" off the ideal tune parameters but some things do change. Most folks want a custom tune that optimizes performance, but we rarely drive that way all the time. So the processor makes adjustments. I ALWAYS reupload my tune prior to my first run down the quarter mile to clear out any negative performance changes the software may have added while I'm babying the car around town.

In general, you need to have a custom tune adjusted when anything that affects air/fuel ratio is changed. Superchargers, turbos, delete plates, cold air kits, cams, ported heads, and even (more so on FI modded cars) long tube headers. Other changes like tire size, gears, etc can be managed yourself from the hand held tuner. Midpipes, maybe, but aftermarket mufflers, no.

One last thing: tunes can be developed for optimum performance throughout the rpm range, or even a segment of it, and even to minimize performance for economy's sake. My car for example was tuned last year to 348hp and was a beast out of the hole and rarely lost the stoplight battles, but the damn thing ran out of steam on the second half of the quarter mile every time--the best I could manage was a 12.40 but this should be a low 12 second car. So I just added delete plates to gain some upper rpm grunt back, and had it retuned. I actually LOST overall hp on this particular tune, but I will likely be MUCH faster in the quarter mile. We'll see at GOOTC in March.

Adaptive learning. I had that turned off in my tune.

One thing you might check is whether, along with that, if the emissions parameters were also turned off!! That happened to me a couple of tunes ago, and I couldn't get them to set values and kept failing the emission test (this is not the longtube header/O2 sensor off/on issue). It took a while to figure that out. Just something to keep in mind...

Yep you are correct. With Adaptive learning turned off it will fail. I have a tune with it turned on just to pass every 2 years

thank u all for this lesson in tunes...
