UPGRADE YOUR FIRMWARE before getting too hopped up on getting it running. You will end up wasting time.
Get tuner studio. I was stubborn and stuck with old stuff for awhile. Heck I had my megasquirt on the shelf for 3 years and never actually made a pass at the track with real tuning capability. Very short sighted of myself wanting to avoid a little trouble that ends up making things better.
Now, if I find out that in the last few months they changed everything to % then Ack. You sure its not some setting you have that is "off"? Most people don't like KPA but after hassling around with it and making my own conversion charts for quick referencing, I understand why its better. I am lazy enough that I used one of the worthless RPM columns (1000 rpms) to convert KPA to PSI numbers (since I won't need the boosted load cells at 1000 rpms) at sea level so I could quick reference in my head what the KPA meant. I also set my stuff up to lean burn while cruising.
Is your transmission setup documented on the RWD6g72 forum? I didn't look recently to see if those Ford C4 bellhousings made it into casting.
I want to throw the same thing you are doing into my Starlet but I am worried a powerglide's long gears would be better for such a light vehicle. Way more work when the c4 stuff is so far along. I have also considered looking for a 2.5:1 Ford 9" and only using 1st and 2nd on the c4.
I've just downloaded the latest firmware and will be putting that on shortly, great suggestions. Also just purchased the full version of Tunerstudios, so hopefully that autotune feature will make my life easy as well.
From the DIYautotune guys, no need for a resistor pack. Just a couple settings in the injector characteristics and the MSII is designed to run low impedance injectors without a resistor pack. Works for me.
Havent been over to 6g72rwd yet, will check it out and start a thread there as well. I've got threads here, at MSExtra, and a couple starion boards as of right now.
But thanks for the info on the % and KPA, etc... I'll do some more reading up on that. I'm still a little foggy on how all that conversion stuff works, so I may still be quite a bit off somewhere.
Still just trying to figure out this:
Note that the scale in MS2-Extra is in %, so 100% = atmosphere (100KPa) in MAP mode, or 100% TPS in Alpha-N, etc.
So obviously a boosted engine will go over 100%.
If 100% is atmosphere, then how much would say 15 lbs of boost be? It wouldnt be 15 X that would it? Theres no way that scale would be that extreme... I read that 1 atmosphere is 14.7 psi, but just trying to figure out the scale... I am just stuck in KPA land where 20 psi ended up being around 200 kpa or something like that, just wondering how different that % should be. I do think the latest MS is all percentage, from what I've read at least.
