hello still verry new to diy tunning.......have read the post on the 165 ecm (The Definitive $32 $32b Tuning Article)i am kinda confused i am running a $6e and i cant find any table (BPW FUEL vs LOAD, msec of inj PW. )in the $6e.....i am using tuner pro rt and an ostrich arap bin......can any body educate me on how to tune the $6e

 

that table doesn't exist in $6E. You might try tuning with the MAF tables. What worked for me so far, was to play with the injector constant to get most blm's around 128, then adjust the 1st few values of maf table 1 for idle. A search will yield so much more info.

 

I wouldn't suggest making any changes to the injector constant unless you have changed the injector size or increased fuel pressure which does the same thing. Just make the changes to the MAF tables. Go with small changes as it will make a big difference. Work on one rpm band at a time and take copious notes. Do lots and lots of data logging!!!!

The ARAP bin has a huge amount of timing in it as well so keep track of the rpm bands where you ping so you can back off the timing. A rule of thumb would be, however much your retard is set for, back it off that much for starters, repeat until the knock goes away.

 

What's your combo? Is it a basically stock engine? What's changed? What problems are you seeing?

ARAP is a vette bin and has some subtle changes that need to be made before it's used in an F-Body. Also, the spark advance IMO is designe to run completely against the knock sensor, which isn't the best idea for a novice. Start with an F-Body spark table.
