Will the stock computer run this combo?

[donsbad68]

Just like the title says, will my stock A9L computer run this combo ok with no chip?

5.0 5spd:

GT40 intake
65mm edelbrock TB
75mm MAF
EGR coolant lines plugged due to no bung in intake
Air Temp sensor moved to intake rubber duct due to no bung in intake
no smog pump
full o/r exhaust
130 amp alt.
155 lph pump
E303 camshaft

yes why wouldn't it? only need computer "tuning" with high boost and high hp i believe

Car still runs like crap, bucks when driving it at lower speeds, CEL light on and off, timing is at 12* and there are no vacuum problems

I am using the stock computer and it runs GREAT!

Computer should be working ok... you got a prob somewhere else... how old are your O2 sensors... TPS voltage... stuff like that you should check often

just real quick, how much fuel pressure? if your MAF compatible with your injectors? does it run hot at all?

idealistically, we should all run 42psi, no more...but since the stock puter is very set in it's ways for fuel timing, it's a good way to offset the stock maps.

also...i'd bump the timing up a couple degrees...just me though.

don, i just read your other post, did you manage to pull any codes out of it with the paper clip trick? your maf might not be playing well...is there anytime it does want to run right?

 

[donsbad68]

problem is fixed! I broke down and went and bought a 20 dollar code reader, and for next to nothing fixed the problem. Turned out the TPS voltage was way too high and the EGR valve didnt have any vacuum! Thanks for the help guys she is running like a champ now!

 

[txstang84]

WOOHOO!!! glad to hear it! and i'm sure your code reader will be used in the future as well...

 

[donsbad68]

im quite sure it will too! I was surprised how accurate and well the little 20 dollar gadget worked!

Where exactly did you get this little $20 gadget that reads the codes, and what is the paper clip trick?
