I did a fuel trim and made some small idle changes.
Looks to me like you have some kind of missfire at 4800... likely where you are making peak cylinder pressure at around 11psi. your timing is up around 23* she is making great power and the injector duty cycle is around 80%

Pull a couple of plugs and post pictures of them for me, if they dont have any signs of detonation we may need to look into getting a hotter spark to the plug. If we do show any signs of detonation, [small specks on the plug] we will want to go to a cooler plug or pull a few degrees of timing.

ok will do that tonight. its like a miss almost so you could be right. i did put a pretty cold plug in it to begin with.

also when im getting on it and let off the gas almost everytime it wants to die unless i rev it up and clean it out. not a real big deal to me. i just want to get this miss figured out i know it will run damn good once its fixed.

i seen EFI Source came out with a new plug and play gold box too..... im drooling over that piece

I personally like the Stinger PIMPxs as it has everything that you can think of.

Plugs are auto lite 23’s

Anti_Hero0932 · Aug 8, 2019

Here the third plug

Replace the plugs and pull 2* of timing in boost.

Anti_Hero0932 · Aug 8, 2019

Rodger that.

Anti_Hero0932 · Aug 9, 2019

those little pit marks, are those the signs of detonation?

a91what · Aug 9, 2019

In short yes they could be. The plugs tell me that the car is burning a small amount of oil and is a tad rich at cruise. Fat under boost (we want that)... the porcelain should not be pitted or rough but it should also not look glazed.
Plugs tell me misfires but I cant see specks of silver in the porcelain. Silver or shiny specks are usually detonation.

Anti_Hero0932 · Aug 12, 2019

got the plugs changed. gotta get some time to mess with the tune and now its raining.... i did notice the plugs had a pretty big gap in them to (the old one) i gapped the new ones at .30

Anti_Hero0932 · Sep 16, 2019

Anti_Hero0932 · Sep 16, 2019

yeahhhhh still around and kicking. i just havent been driving the car much. that black car is pretty hot right now with no AC.

im hoping this fall i will get some use out of it.

Anti_Hero0932 · Dec 24, 2019

Getting someinterior work done. My driver side seat belt won’t retract anymore, the passenger side works half the time. Changing the gear out for a 3.55. Also putting some plywood in the hatch where the spare tire cover was. It’s a half moon shape now so wanting that to look a little nicer too

a91what · Dec 24, 2019

Anti_Hero0932 · Dec 26, 2019

General karthief · Dec 26, 2019
