I saw there are countless posts about converting to the 89 arap bin from the 88 bin. I couldnto find clear answeres to my questions though.

I am converting the prom of a 88 305 TPI Auto, The car has a modded exhaust and a 1989 L98 cam. (206/213 0.415/0.430).

What do i have to change in the 350's Arap Bin? I already reset the injector constant to 19.01, I added valuses to 4-8 of the Crank Fuel PW Multiplier vs. Ref. Pulse to make up for the cold start injector. I restet the temps for the fan.

What if anythign has to be changed more for this chip to work flawlessley with the new code? I am not lookign for instructions to make a 100% tuned chip on the first try, just dont wanan blow anythign up and i want my cooling fans and TCC to work right.

I am using Mansur's GMECM Edit to modify my bin.

Tone down the spark tables - they are a bit too aggressive IMO. You are aware that you'll have to disable the cold start injector also? I assume you've done a search and read everything on "ARAP". If not, do so.

Do those things, along with the one's you mentioned and start burning and testing.

 

Yeah i know about the injector. I have read everything on the site about arap. I am a fan of search, Usualy find the answers faster. I just had a few posts confuse me

Ok, i did some modding to the arap bin. What do you guys think of this

I checked the N/0 box, Added values to the table so the car starts right, I changed the spark table to a less agressive version based on a 89 305 M6 and 350, Changed the fans to come on sooner. set the injectors to 19.48 and thats about it. Does this have a chance to work decently in a 88 305tpi with the l98 cam? I donot have acces to a programer often so i am tryign to get it good the first time. I am not lookign fo rthe perfect chip, i just want it to run right w/o a ton of detonation and it drinking gas.

I would run the spark table from this bin.... ftp://ftp.diy-efi.org/pub/gmecm/bin_...6E/AUJL 6E.bin

If you are using the 305 19lb injectors then try a constant of 18.5 or if you are running the 350 22lb ones use 21.5. This should help with the cam and other mods you have at WOT until you get a scanner...
