Another thing that worries me is my cluster going ***** nilly at high speeds/rpm but usually not in first gear. My Tach, oil pressure, and temp gauge go a bit crazy when im at highway speeds or high rpm. It didn't do this before I pulled my motor, so I assumed it was a ground somewhere, but from what I can tell, they all look fine.
Fixed my boost creep issue, and switched the map sensor to be T'd off from the FPR and then T'd into boost gauge and map sensor. But still want to get the finnicky gauge problems and the light load misfires so I can get better than 15 mpg. I'm thinking about just replacing the engine ground on the exhaust side. I don't know what else to do.
This is getting really frustrating. I replaced the grounding strap from the engine to the firewall, and sanded down the contacted for unpainted metal and the gauges are still going nuts at high speeds/rpm. IDK what else to try
BTW, on a '90, the oil pressure gauge can be an excellent detonation indicator. It is located at the perfect place on the block to pick up det (where the knock sensor went on later models). Might be worth backing down the spark map to see if it goes away. If it does . . . you owe me!
Anyone feel like checking out my tune? Whether for help or curiosity, I don't mind. But now that it is cold, my car is refusing to start and I already fouled some plugs. So it is time for cranking PW/ASE/WUE tuning. I have been dong research and for what I could find, my cranking pw is EXTREMELY high compared to what I've seen. Mine being in the hundreds and others being in the single digits. (Edit: I think I have confused them with something else). Idk if MS3 is different than 2 or what for those settings. I have attached my tune and here are my settings. I was hoping for any input before I dig in. Thanks.
Alright apparently I lied about fixing the boost creep. I had the turbo ground out some and I thought it fixed it but I just wasn't driving it like a man and it still creeps in 3rd-5th gear. I got a full 3" stainless exhaust put on over the weekend. I hoping it would help but it srill creeps. F me, right? I guess it's either time for more porting, opening the hole a bit more, grinding behind the flapper, or ewg :(
