I was very happy with the 231E update. That's what showed gains. I FELT that. When I came back for the tune, I didn't feel anything worth $1000.

Keep in mind that even though you saw negligible gains on the dyno, on the street where it really matters you very well may have gains.

At speed, the IAT temperature is usually between 10-15 degrees of ambient temperature. So if it's 75 outside, at 80 MPH you'll have an IAT of 87 degrees.

Now stop the car and let it idle for 5 minutes, or run it on the dyno a couple of times (even with dyno fans). You'll see that the intake temperature is over 110F, even up to 140F depending on the number of runs, air flow, etc..

Then you flash the tune in and run it again, and are disappointed that it didn't make 20 whp more.. You'd be surprised with the amount of ignition advance retard and power loss from a 40 degree difference in IATs. I see stock cars on the dyno unable to hit the stock targets, but on the road they do. In the end, if you have a serious wind tunnel and a controlled and measured environment, the dyno is a very useful tool. But given that 99% of dyno testing is not in this kind of environment, it's not really an accurate representation of what happens on the street/track/ etc.

See above. This is all dandy but I didn't feel $1000 worth of placebo awesomeness.

I sent your tune back in February.

I asked for your original tune and got that back on the 1st of Feb.

I will resend the links for the 240E update again with the tuned file.

The error could be on either end but let's just assume it's on ours for now.

Thanks Sal. I'm not sure what happened. Regardless, I have received the new file you sent today.

I will flash the car to 240E and drive it around to get some new impressions of the tune. Hopefully I'll be more impressed than last time.
