Good Morning every one heres a my problem its a 1992 firebird formula with a 350 tpi stock heads with three angle valve job and slight bowl work, runners, and base it has a mild comp cams cam about 10:1 compression. the tune i am running is a axcn bin i have inj flow set i have the oil temp changed to pressure. the car ran for about a day and a half on the tune and now it will not start but when you remove the piggy back chip and run on the stock 350 tune the car will start but it runs horrible. ive noticed with the key on and the axcn tune applied the fuel pump runs consistently and when you crank the car all the dash lights come on except the shift light b4 when the car started with this tune the light would come on i have tryed to to reburn the chip a couple of times but it has no affect. my next step is to try a differnet bin all together like the arfp bin. any help would be greatly appreciated.

THANK YOU
Bill

 

How was that done, Code change or ADS tweak?
If using a 512 chip be sure to erase it before burning.

 

i unchecked Switch 24C Error Code Masks (52-63) - Bit 7 - 52 and Switch 24C Error Code Masks (52-63) - Bit 1 - 62 in the flags.

I am useing a 512 chip i double check b4 burning to make sure the chip is blank in the buffer. i have not used an offset to program the chips could that be my problem im still kind of new at this but im learning what is an ads tweak?

thanks
bill

 

Bump

 

well i had a chance to mess around with the car this morning burned a chip again but it in and still nothing i looked at the dash and noticed no check engine light pulled the chip out and the light came on solid turned the key off waited 10 seconds turned it back on solid cel no blink went and put my stock 305 prom in turned the ign on and had a blink and solid cel so i guess i have a bad prom

 

Yes, need to offset the chip for the burn/flash. You are putting a 256 kb BIN into a 512 kb chip, so need to offset it to the upper half. Or stack the BIN and burn/flash that.

Always look for the SES blink, saves a lot of aggravation.

Thanks Rbob

One more question I havent had time to do much research yet but whats the difference between the 305 esc and the 350 if I were to place my g1 adapter on my 305 prom and run the axcn bin would it work
Thanks bill

 

The center frequency and gains are different. But it more or less works.
