Tuning question? Speed density problems
Long story short, I have a stock 6.0 with a single turbo in a 71 Nova. Attempting to start the first time I only have spark on #1 cylinder and it is really fast. No spark on other cylinders. Tech 2 shows 3500 RPM key on engine off.
Its a 99 F body computer that has been tuned to speed density, the rev limiter set at 3500 for a base tune, and E85. 95lb injectors.
I plug in a friends 02 Camaro computer and it has normal spark on all cylinders.
Today I get a new PCM and have the shop flash like before, back to the same problem.
What are they doing wrong?? I covered all the bases on my end and it works great with the stock PCM (cant start due to injector sizes-E85-etc)
