Dynaspark

 

Is that like the Delphi optis? Im replacing mine with an ac delco one, which would be the best choice?

 

It all works the same. The dynaspark is made much better but is also more expensive. Take a minute and read up on their site.

After receiving mine and seeing the quality put into the dynaspark, I would not hesitate to get another one if needed. I know of a few high horsepower LT1's with this unit and they have had zero issues.

 

 

I would have to agree with everyone else on the #8 pigtail issue because if you swapped the injectors out and the issue remained it must be the wiring.

 

i had that problem on a sbc had to readjust the valves

 

I was inclined to think that at first also, however I had the same problem on a different set of heads, cam and intake last fall. So 2 different combos with the same problem makes me think it's something external to the engine.

 

Changed the injector pigtails on #2 and #8 last night. The #8 primary is still getting extremely hot after only a few minutes at idle. I will pull the spark plug out today. It was too hot to get to last night.

 

According to Ed Wright LT1 ecms CAN in fact tune individual cylinders.

I would look at that injector ASAP. I would not run the car until I figured that out.

And FYI Single planes are notorius for corner cylinders being lean, it has to be corrected with porting.

My car has hurt #8 two times now. I had the intake ported this time.

 

Yeah, I think you're right (and Ed of course). I found the "Individual Cylinder Fuel Trim Multiplier" table in CATS Tuner for tuning the cylinders but everything in that table appears to be normal. I tried swapping #1 and #8 injectors but #8 was still a problem. So I don't think it's an injector problem. After talking with LE this morning, I may have a weak spark to #8 which is causing fuel to be burned in the primary instead of in the combustion chamber. I plan on picking up some plug wires this afternoon and trying again. #8 is hard to get to and I very well may have damaged the wire taking it off/on and it's the one thing that has remained the same across builds.

Thanks for the suggestions. I will let you know what I find.

 

engine bay/intake=

that's how the air intakes should have been from the factory! bastards!
lookin good tho!

 

I found the problem. You should have gone to a real school, like UT or something

Jk car looks great cant wait to see out it again, hopefully you get your problem fixed

 

Lloyd Elliot gets the cookie! It was the plug wire. Kyle will chyme in shortly.

 

happy to hear thats fixed... now lets see some video!

 

Agreed

 

#8 read around 150K ohms! 6 wires read around 500 ohms and #3 read around 2K ohms so it was probably on it's way out too. I picked up a set of new wires and got them installed. Fuel pressure looks to be a few PSI low but the primary isn't glowing anymore.

Thanks LE!

Vid!!

Hump worthy

 

Looks yummy! Sounds great, man.

 

No need to defend that error. None of us is "prefect". LOL

Was really hoping you wouldnt figure out the problem. Cars get real cheap in moments of frustration and I was willing to come take it off you hands lol. Sounds and looks great as always. Wish I had your patience
