I went to Balanced Performance today in Atlanta for a drivability tuning session on the dyno since the car (black 94 MR2 Turbo)was running a bit rough in some places and a bit lean at low rpms under vacuum, and had never been tuned since the addition of the RMR intake manifold and the removal of the CAT. The timing from the previous tuning was very aggressive, so that was relaxed which actually netted an additional 12 HP. The previous fuel curves were not bad, but are definitely cleaner now. Ed Semf from Atlanta did all of the tuning work today. The results were very positive and the car idles and drives much better. The Air-to-water intercooler performed beautifully with intake temps rarely rising above 95 F degrees, with the highest we saw all day during a pull being 111. Higher boost runs are planned later once I get rid of that POS Profec A "fuzzy logic" BS boost controller.
I'm looking for an older Profec B spec (not the new one) if anyone knows where I may find one. I'm also planning on changing the turbo from the T-66 to possibly a GT-30 in the future.
Conditions were as follows:
77.78 F, 28.61 in-Hg, Humidity: 48%, SAE: 1.05
All runs were done at 14 PSI and 93 octane pump gas.
The final run of the day netted 337.92 HP and 277.09 Torque at 14 PSI.
