It's been close to 2 years on this build, but finally got to the point of getting the MS2 installed, wired up, and hopefully ready to breath life into this gal finally. Problem is, I am lost - I am far from an expert when it comes to tuning, especially when it comes to the ignition, so I am reaching out, hopefully won't sound too stupid, and hopefully get it to at least fire and idle sometime soon.
Ok, here is the high level. This is a total custom project that I purchased before it was done, and made some modifications to it. Changed the transmission to a c4 auto (going to be mainly drag car but still street legal), changed the ECU to MS2 customized for use for 3 X GM MSD coil packs, and some other things that really don't matter for the tuning/programming discussion.
Be gentle, I'm a newbie with a LOT of this stuff. hehe
The MS2 was purchased through DIY Autotune and they modified it to work with the MSD coil packs, i.e.:
Here is the list of how the MS2 was built:
The motor has the 92' style sensor on the back of the cam, from what I was told it has the cam angle and crank position in one sensor. It's a 4 wire sensor, power and ground, and what I'd assume is the crank angle and cam positioning signal wires.
Here is how I've wired up the car - no idle air controller or step downs, very basic config:
I am currently using EFI Tuner Studios instead of Megatune - not sure if that is ok or not, would like feedback on that as well, but can't see why it'd be that different. Here are the fuel and spark constants - I am 99% sure I am 100% incorrect on these
But as I've mentioned, I really just don't have a bunch of background there. The old g54b starion motors were a lot simpler, and the aftermarket ECU I used on that set up came pre-programmed, so I never needed to dive this far into it.
Additional spark settings:
Additional fuel settings:
So how far off am I really? Current status is, on turning the car on, ECU registers with the laptop, fuel pump powers on, fuel pressure rises to 40psi and holds, no leaks. Crank the car and starter engages, engine turns and basically sounds like it is trying to start without a hint of spark.
Any information, direction, ets, would be greatly appreciated. I know that the initial start is the hard part, and after that, I've had very good luck with megatune in the past - it's just getting it to run.
Thanks in advance! Hoping you can help me bring life into this gal!
