hi everyone .. i don't know what is going on with this car..

camaro Z28 A4 1998

Lt's + lid + LS6 Intake + cat back (stock TB & maf )
TC 3500 2.5 STR
cam 228 / 232 .588 . 595 110 + 4 lsa

New Tr55 + MSD 8.5

see the log file and tune file.

1- there is alot of KR at idle (it's timing or something else )?
2- after hit the gas the RPM drop down to 200 / 300 and go back to 800 /900
( see the frame 2660 to 2760 )
3-why the result at this map came like this ??

i don't have WBo2 ( the VE table like stock)

 

I dont know about the KR at idle, but your T-Cracker airflow looks like it came from a manual car. Also, your T-Follower settings in-gear look hinkey. Did the KR start after you increased your base spark tables at idle? 31 deg seems like a lot for a cam that size. I am a 6-speed guy however, so I am not totally sure about the cammed Auto cars.

 

try your base spark at 9 to 15. should get you a good start.

 

thanks for replay
i'll try to lower the base spark ....
BTW...
RAFPN MAP .. all time get the same result what is the problem???
