Thanks! I will just tweak the main timing table slightly.
Finally put the engine back together and ready to modify the timing tables. What I noticed that the bin for f-body has spark advance table bias zero, and b-body has it set at 20.
Do I just leave it...
I agree, quite a difference. Perhaps the bin I have is just different, or 94 was was different, idk..
Is there a way to monitor the knock? I have never experienced a knock on this engine and I am...
Thank you all for good advise.
I compared the bins for a 94 Firebird ECU I had as a spare and original Fleetwood ECU and found that the Firebird timing tables are more conservative at higher RPM,...
I should have mentioned that the engine is used in a 53 GMC truck, which is roughly 3000 LBS or even a bit less.
I am definitely going with aluminum heads - because they are lighter and well.. I...
Hi all,
I am currently rebuilding my LT1 out of 94 Cadillac Fleetwood. I have a pair of aluminum heads and a cam out of 95 Firebird that I wanted to use to save some weight.
Can anyone advise if...
Yup, I have a button with LED wired just like you describe and it lights up properly.
Thanks!
Just checked again and if I set View Filter to Hacker there are two things happening when I press Perf mode button:
1. Performance mode button pressed flag will set to Off momentarily while I am...
Yes, I did. As soon as I click Stream, data starts populating. Maybe I did not look good enough. Or engine should be running... I will double check.
Tried checking parameters on Trans tab, but did not see anything change. The engine was not running, ignition was on.
I will be checking tomorrow. Thanks
I hope so. The truck is not on the road yet. It will be a while.
Thank you all for your help!
That parameter did not help. However I changed both of these parameters
Force manual mode in D2 changed from Set to Not Set..
Single Manual/Perf Mode Switch changed from Set to Not Set..
And the...
Update. A/C is kicking in now - I flashed original B-body bin and AC works.
The situation with AC request not working after manually commanding clutch to engage is resolved too - it was just...
Original Fleetwood bin did not want to turn perf. mode on no matter what I have tried. As soon as I flashed Firebird bin (i had to match multiple parameters to original bin, like shift points,...
Steve, you are correct. Thanks
Dave, thank you, I will take a look. Is there a specific parameter you have in mind?
Hi all,
I got a 53 GMC truck with LT1 engine/4L60E transmission and PCM 16188051 out of 94 Fleetwood.
I installed an aftermarket AC system and wanted the compressor clutch to be controlled by PCM....
