Guess you'll have to start looking for those "student discount" dyno runs now that the chip has had a while to "learn"

No Dyno Puls for a few months... Summer session is coming up and that means I need to $hit about $4,000 to pay for college over the summer ... Hopefully at the end of summer I'll have the finances in order to do another Dyno Pull...

Disconnected the Battery all through the ECU swap... Reconnected the battery after the ECU was back in the car and did the first Stage 1.v5 run about 5 minutes after with the ECU still dangling (didn't have the time to crawl under the dash and put it back in there while I was on the dyno and 15 other cars were waiting to get on there...

Interesting was that I looked for the "hesitation" I used to feel around 3k RPMs and couldn't seem to find it based on the graphs there. Did your car on the stock ECU ever feel like there was a slight loss of power around 3k? Like, it would delay a little there before revving higher?

Anyway, good to see graphs finally posted. Too bad the whole "re-learn" thing would invalidate the data (different day, weather, dyno conditions, etc etc).
Nope, I never really had a hesitation... The performance was kinda random at times, but only barely noticeable... THe only one that could tell that something was alittle different when I'd get on it with the stock ECU was me, but that's because I've owned my baby for 7 years and know almost everything about her

I'll volunteer to go back to the same Dyno and swap out ECU's again... I'll need a stock, functioning 1995 ECU though (and no I don't have the $$$ to buy one)... I'd only if there isn't complaining about the weather conditions... Wether conditions will NEVER again be exactly as they were that day. It is something that is just going to have to be dismissed as an uncontrollable variable... I will say however, that National Speed's Dyno is located inside an air-conditioned and ventilated workshop. So for the most part the weather conditions have a minimal impact on the runs... The day I did it however they left the shop door open so that all of the 30+ people that were there for the meet could get pictures and whatnot...

However since we can pretty much rule out weather as a factor at the moment (atleast till it's summer in Wilmington, NC), Then my stock ECU runs should be a good basic place to start... The reason we did 4 pulls is because the car kept making power, slightly more each time...

I will say that I think the chip effects fuel economy alittle (in the performance map)... I just got back from an Autocross in Wilmington a few hours ago and only managed 21 mpg down there and halfway back... That's a few less than what I would normally get... However, I don't know if that was a great test since I spent most of the time driving down to wilmington behind a Corvette Z06 and another car that were doing 90-95 the whole way down... We made record time, but I could have sworn that every time I looked down at my fuel gauge, it was slowly creeping down towards the big "E"... I am heading to Charlotte to see my grandparents next weekend and that trip will be done at a much more conservative pace (70-ish mph)... Normally with a full tank and driving at about 70mph I can get about 25mpg... Just filled up on my way back to Raleigh tonight so the only miles on this tank so far are highway miles...

If I missed anything just let me know
