welcome
Its interesting your is so much different. Maybe we are looking at different tables. Mine is cranking afr but yours just says afr? Maybe they are the same.

Thanks. Fuel pump can be heard running when key is turned on.
All interesting observations. Thanks everyone. Today under the choke table for afr vs temperature when cranking i decreased the afr and it started cold in what sounded like 4 engine revolutions....
I'm resurrecting's my old thread. I'm working with the 7747 ecu. Under the scalar parameter "engine startup rpm" the description says "ENG Start Up DRP Periods. Setting affects idle spark.". What are...
Welcome
I believe these are the injectors i got from autozone. GP Sorensen Fuel Injector 800-1807N
Understood. Most things are new cts, injectors, heated 02, tps, new entire tbi wiring harness. verified base timing is set at zero degrees. Im not going to get crazy with the tune as I have another...
Alright. I changed the spark table to a starter table more appropriate for my heads. I changed the BPW to 155 with the engine all warmed up and in closed loop. This got my BLM and INT right at 128...
ok. thanks
Ok. I will alter the BPW to try and get some rich and lean fueling then start messing with ve and spark.
Should i mess with the BPW or should i start trying to tune the fuel tables and leave the BPW alone?
I have a 1978 chevy k20 with the 350. I just put a melling ccs-2 camshaft into it. Duration at 050 inch Lift:194 int./202 exh. Anyway when the engine is first started and warming up the throttle...
I got the issue solved. Turns out my valves were adjusted to tight.
I just replaced the camshaft in my 350. The timing set is new and the cam and crank gear are properly lined up with the dot on each gear pointing at each other. I verified the harmonic balancer and...
Welcome mike.

The memcal or calpack or netres whatever you want to call it is like a super basic backup chip that can run the engine if the main chip fails. Its the chip that operates the engine when its in limp...
The 1227747 ecm is just a computer to help process the data. When you customize the actual chip with tunerpro that is where you can change how many cylinders the engine has, fueling, spark etc. So im...
Have you considered purchasing a burn 2 to program the 27SF512's?
Ok thats what i will do. Thanks i just wasnt sure if i might run into issues but it sounds like all will be good. Then i can tune.
I have a stock 1978 chevy k20 with the 5.7l engine. I converted it to tbi a long time ago and im using the stock 454 tbi spacer as my adapter from the tbi to the carb pattern. Everything is all set...
So he changed the cap rotor and wires and the issue of the truck gaining and loosing power has disappeared.
I'll post an update when he changes the parts.
