The BLM's vary from 108-130, integrater is arround 140 or so, the motor finally holds a half way decent idle now (thanks Neil !) but it's doing some weird things. The knock sensor is pulling 2 - 8 degrees of timing out at any given time. The motor has a miss sometimes. I figure it's detonating randomly and the more I drive it (length of trip) the worse it runs. Tempature never gets above 185*. It runs the same in closed loop as it does in open loop (while car was running, I disconnected the o2). TPS voltage is 47 at idle (850 rpm's) and my sensor isn't slotted, so I cant adjust it. Where would you guys go from here and is anyone interested in looking at my .bin to see what they think?

Thanks,
Mike

Anyone?

Possibly way to much timing?
What is initial set at? Is the prom set the same?
If you want to mail me a bin ill look at it ,but would be much better off sending a scan file.

Have you been playing the use the wrong fuel injector constant to get the fuel right **method**.

For the BL to be less the 128 means it's right.
So it would seem you've got too much timing.
Try cut and posting your main spark table here. Or as an attachement.

Base (mechanical) timing is set to 6* and so is the PROM. Injector constant is set to 23#. Fuel pressure is set to 43 lbs. at idle. The car is bogging and occasionally detonating and or missing in both closed loop and in open loop when I launch the car and timing is being pulled out (knock sensor related) when I nail second and third gear. 4th, 5th, and 6th seem to be ok. I'm starting to have a feeling that it's more on the mechanical side.

Also, what is the correct TPS voltage for a speed density TPI motor at say 850 rpm's? Mine is reading ~45.

It's kinda weird, because the whole time, the ECM is not throwing any codes!

I'll try to get a couple of saved scans (diacom plus) soon.

Exactly what table in tunercat do you want me post?

Bare with me, still a newbie!

You're running injectors rated to flow 24# @ 39psi...you have your PROM set to 23# and you're running 43psi. This is what Grumpy was referring to...recalculate your injectors' flow and use the right number. Offhand it's probably in the 25.x3 range.

And no, I'm not baring with ya...you wanna burn chips naked that's your thing, I prefer clothed.

Update: I worked out a few bugs (mechanical) and the car runs pretty damn good now. I also changed injector constant to 24# and lowered fuel pressure to 41#'s and raised base timing to 8*. All of which helped dramatically!

Ok, now I'm stuck from here. I dont know what else to change to futher performance. The only thing I could do from here is provide someone with Diacom plus scan data and then show that person my .bin. Eventhough shes running strong now, I still feel that there is more to be had. If I provided this data and my .bin, could or would you guys point me in the right direction?

Again, all advice from you guys IS very appreciated!!



Thanks,
Mike
