Now with a forced induction car, eTuning works really well, because in addition to the standard fuel, timing, cam tables that are optimized...we are also making the most important change with respect to power output: increasing the boost level. On some cars, it's not uncommon to see 50-100whp improvements from forced induction eTuning.

I've seen a few NA cars come in with lots of mods, and AF ratios in the 14's at WOT! Talk about poor power, and high danger!

i thought the computer is able to adapt to small mods. i just have the stillen intakes and thats it. shouldnt the computer be able to adjust for that? or are you talking about intake, headers, test pipes and cbe.

It adjust for stiochmetric conditions at idle and cruise. At WOT, the level of correction is much smaller even with the new OEM wideband sensors from the factory. This means the fixed base fuel table is still the critical map to have correct.

But if we have datalogged our normal driving and sprited runs, such as is requried with Uprev, would that not suffice for minor mods?
I would think it more critical to have a turbo car actually on the dyno that a simple bolt on mod NA car. |

Then you get into ignition timing, which is a whole other ball game. You cannot tune timing based on a data log without real time feedback from the dyno. Camshaft timing is the same way, the tuner needs to see if his changes are making a positive change or not, based on dyno feedback. |

i would always recommend a tune in person vs a mail in tune. i never really bothered with N/A cars but all my turbo cars have always been dyno the street tuned, there is no other proper way imho.

My FI cars (supercharged Stang GT / SR20DET S13) were always dyno tuned. I feel comfortable with the mail in tunes. I do not really have a choice anyway.... I am not going to SRD in AZ and trusting them with my Z. That is a Honda shop and they have messed up several Nissans that I have seen in person. WOW.
Chris, I think you hit it; you may not get it right the first time, so it could take several tweaks. If I did have a reputable Uprev tuner in AZ, I would be all over it... |
