embedded code 2.36, megatune release, 283sbc, tpi, 8pin hei

since loading the newest embedded code into my MSII things have been going pretty good. For the most part the engine runs very well. the problem seems to be at lower rpm, especially when in gear. The engine will run fine and then die for ...

loaded the embedded code 2.36 and am now running the release megatune. The car runs absolutly amazing!!!! It ran well before except for the higher rpm, now it pulls right past 4000 up to 5500 where I set the rev limiter like an animal!!!! I think the smoothing factors or something are making the ...

I dropped the distributor in at 10 dbtc pointing at number 1 with the "teeth" on the reluctor lined up.

I will load new code and run the new megatune, I probibly should have done that anyways.

I will let you know what happens.

Thanks,

Matt

well I went ahead and stripped out the module from my dads roadmaster and put it in my distributor. The car runs alot better, but still cuts out alitte, now at about 4000rpm. I am going to buy some msd super wires that are soppused to have like no resistance and still have tons of surpression.

I am ...

MSII embedded code 2.1, megatune 717, gm small cap 8 pin hei distributor, tuned port intake, 283 sbc, autolite 26 plugs.

The engine will fire right up and idle great when cold, and also restarts fine when hot. With the engine in park and no load it will rev fine, but if I slowly advance the ...

283 sbc, th350, tpi induction, small cap efi distributor, MSII, megatune 717, 48 lbs fuel pressure one the rails when not running.

So My car is running and things are going ok so far. When the engine is in park with no load it idles great and revs fine. When I put it in gear it idles fine and pulls ...

sounds good.

I think I will try tuning the tps accel and try running 100% on tps accel. I have read that placing a small fuel filter in the map line may help, so I might try that also.

Thanks for the replays, I'll get to work tuning!

quote: "for a quick test put the proportion to 100% tps
and/or crank the mapDOT threshold up to maybe 100 - 200
see if that stops the AE from trigering."

I did that and it just sat there and idle like factory!!!!!, the tps accel did not turn on at all!!!

Now the question, what is causing the map ...

I'll try that today.

I don't know if this would matter, but when I wired the 8 pin hei I spliced into the 5v ref for the tps, ran it through a relay and a oil pressure switch so there would 5v only when running. also when I calibrate the tps a window pops up and says the values "look funny" I just ...

283 sbc, tpi, MSII, embedded code 2.1, megatune version2.25b717

I ended up changing my cam after realizing that the old cam would never work with my stall converter. So I broke in the cam tonight and the engine sounds very good (no misfires, stumbling...) I have not driven it yet, just running in ...
