Anyone care to speculate? I'll scan and post the sheets tomorrow evening, my appointment is at 10am. I'm going to do at least 3 pulls, maybe 5 if I'm making tuning progress.

I'm a bit wary...my rebuild has shown low compression and the front rotor faces are uneven so I may not be up to my potential.

Anyway's here's my mods...

Wish me luck, I have some late night tweaking to do with the FJO and datalogit....I'm going to run up to 1-1.05 bar so let's say 14psi or thereabouts at 11's in the upper AFR regions.

 

Duh...

 

Just FYI...my best was 356 rwhp. Can't scan in the sheet right now but after 3 runs in the 340-350 range I went to 300's and lean with similar (and then the same) maps.

Any ideas on what would have caused such a strong drop? Air Temps, Water Temps, Oil were all around the same. But my last 3 runs were all crappy and the car leaned out where it had been fine before even after I put the maps back.

 

sounds like massive ******* heat soak, but your air temps don't reflect that. by air temps do you mean intake air temps?

 

Well that's what I was thinking ( I did a bunch of runs, like 11 over 2 1/2 hours) but the air temps as recorded by the PowerFC stayed around 39-44c the whole time.
