255 Walboro. I got ya.

Hey guys, so since I got all the bugs worked out on my car I want to start moving forward with some things. I basically want to add a small nitrous system to the car, the car is HCI, and bottom end...

So still waiting on Comp Cams.... I ordered a pin from Crower/Lunati. The Crower pin is 1.188" from end to end, which is the same as the pin that we pulled out of the cam. This appears to make it...

Man I'll be the first to say I feel like a dumbass for not finding it sooner but just my inexperience with the setup I didn't check the pin. My best guess is the dynaspark is a billionth of an 1"...

Thought I would update. Can't stand it when people never post what actually fixed a problem. So I don't get to work on this much because of my busy regular job and being a single dad with a 6 year...

Well after today it may be WTF wire problem. I disconnected the MSD, replaced ICM, also fixed some suspect ground wires. We fire it up and Voila! Idles perfect no codes, crisp throttle response. I...

Thanks Jeff. I won't rehash everything but the car has been data logged quite a bit. We have scoped opti and it looks fine. Shop is in the process of checking wiring harness and have already done...

So thoughts on the Torqhead setup? I have read some positive and negative things but it seems to be pretty solid overall. I was planning on ditching the opti in a year or two but at this rate I might...

Going to change ICM, just because-can't hurt. CPK timing was out of spec immediately after replacing the original Dynaspark and my mechanic said this. I personally was confused on this and the...

Uh yes it runs. Therefore the timing numbers, AFR, stuff included in the quote you used... This chart was very helpful however it seems that info is incorrect? Was just trying to be sure I am not...

Yes so I am guessing that -"B.) if pulse is present, ICM is faulted. Replace and return to step 4".... Is not correct on the trouble shooting chart?? Lol, I am just trying to figure out if I am...

Worked on it a bit to today with mechanic and have a little better understanding. Tested grounds, ICM, used the optispark troubleshooting chart on the website here to kind of eliminate things. Which...

Tuner was Mo Bailey, from what I understand he is good. This car did sit for a quite awhile though so I really don't know what all it might require. I saw the posts on timing advance regarding how...

Wanted to add no knock codes or indications on the sensors. My first thought was that the dowel is not located correctly and is in that clover area. However it looks like you would have to force it...

Thanks for all the info. The car ran bad ass with the Dynaspark mid-range, top end, WOT. However it would be hard to start every once in awhile and would afterwards go P0372 code. I also noticed low...

Yes, to my knowledge the CPK on 96 and up cars only provides OBD2 codes anyway. Doesn't really control anything. I believe though it probably is working and it sees the timing is out of spec, and the...

Hey folks. Looking for answers if possible. Bought a 97LT1 Firebird HCI car. After having it a few days it pulled a P0372 code, usually directly after it took a few times to start. Car seemed to run...
