Here is the dyno graph for the Aero with the LET ECU tune. Runs 1 & 2 were from today and he put the high run from before the tune as run 3 for comparison. It was 96 degrees today and the first dyno was at 78 degrees. I am not happy about only getting 8 hp gain and 15 Ft-lb of torque. I expect that this is due to the crappy temps, it is 103 now.

Note the shift to lower RPMs where the torque takes off. This is probably what helped reduce my 60' times into the 1.7 - 2.0 times. The other interesting thing is that the AFR is still running at 11.4 avg. But the max AFR is up from 12.3 to 13.9 avg.

I am VERY happy with the LET tune and the improved performance of the car. I was just hoping to see better numbers. Guess I need a set of improved intake manifolds. I think I heard a rumor about someone making some.

Iam planning to go with the club to get another dyno with my h/e and code 3 pulley this year. Look at my dyno sheet, that is with my intake gasket matching / let phenolic gaskets / and a MUFFLER delete, not resonator for comparison.

Did you have street tires on the street to get your 60' times or were they from a track with slicks?

Woody Enjoy

PS you wanna look at the torque curves, I breath better, you have more bottom end I believe, W

 

Woody, yes there is more low end torque and the car feels great. The 60' times are with street Kumho Ecsta SPT's. I am going to go to the track next Thursday if this mini heat wave goes away. I think I can get to 12.4 if I can get the launch down and its not too hot.

I have the JEGS surge tank and need to install it and seperate my IC cooler. I also have the 6mm phenolic spacers and Johnson pump to install. The next thing will be adding the extra IC cooling coil like you did. Thanks for all the informative data in your expierments. Keep up the good work.

Thats not to bad considering the weather conditions. Wait till fall, then you'll see the real gains.
