Have a 71 Datsun 510 that I just finished installing an S13 SR20DET engine. Purchased the MSPNP2 a couple of months ago and just curious to see if anyone is running an SR20DET with a MSPNP2. I am at the point where it is cranking, but not successful at getting it running yet.
As far as engine components, I have 550cc injectors, splitfire upgraded coil packs, t3/t4 turbo...

You do have a computer connected and running with tuning software while you're cranking? Can you see rpm?

MS2 won't work with the stock CAS trigger disc you need this: http://www.diyautotune.com/catalog/50-m ... p-472.html

That is included with the MSPNP for these cars, and is covered in the installation documents, along with setting the timing. The timing is set correctly, right? Just checking.

Can you post a data log of an attempted start and a copy of your tune file?

Here is a copy of my data log....

Battery is pretty low, not much else jumped out at me.

Please check timing and post the MSQ.

Here is what I am using...timing is correct

This doesn't look like a standard MSPNP tune. Try rescaling Required Fuel; it's a bit low for your injector setup. Also, change the injector drivers setting to "Additional Drivers"; MSPNPs have four injector drivers, and setting this to "Standard Drivers" turns off half the outputs.

it is the msq I downloaded from the DIYautotune website...

Do you have a proper base tune for the s13 sr20det red top??

Use this one: http://www.megasquirtpnp.com/downloads/ ... T_331a.msq

Is the IAT sensor reading accurate?

How is the timing when checked with a timing light?
