Hi Guys,
I'm just getting started with my new MS3Pro setup and wanted to get some 'pros' to take a look at things.

Here are the files.

Current Tune

Logs

The car is setup with RX7 550cc injectors (yeah I know, runs fine). Water/Meth progressive pre blower 80/20 (walmart -20), 10psi pulley (less with water/meth). Ported 99 head, bp5a cam, JR header, 94 bottom end. Standard 93. FFS, so no intercooler. I'm seeing around 160 IAT's at the top of 3rd with very poor air intake placement.

This 'tune' should be super conservative at this point, just setup from the base maps with some autotuning on road. It drives pretty darn good, much better than my old MS1. The only issue I've seen was that in elevation and really pushing the car it felt a bit unstable and the afr's started to get rich, power cycling the car/ecu seemed to drop the AFR's back down.

Let me know if you see anything off and where there is room for improvement.
Thanks
Andre'

Sounds like you may need to tweak the baro correction curve. Make sure baro correction is set to two independent sensors.

Wow. 160 intake temp? ???

Andre94R

Thanks for the feedback Matt, I've adjusted that moving forward.

Anyone else have any thoughts on the tune itself?

BTW Ryan, it's not intercooled and can't be.

Why can it not be intercooled?

Andre94R

Because it is a coldside complete intake manifold with the supercharger bolted on top.

That's no excuse.

This is for an M90, but you could make one for the smaller blowers on the FFS setup.

Right, I agree it's a limited design but that isn't the point.

How does the tune look?
