hey keep us posted on this. I have a friend with a 92 VR4 we are debating running MS-II. He wants to get rid of the MAF and go SD.

I run in 4 squirt mode, going to 2 wont even start...i still havnt figured out why...

cranking pulse should have nothing to do with 2 or 4 squirt, because it squirts all 8 injectors at every ignition event right?

i've just been tuning VE table for right now, i want to get everything + or - 5 ...

Last interval has help a lot! I've been out driving for about 3 hours tonight using autotune and a little MSTweak. I just need to enrich the high load areas a bit and lean out the cruise parts and I'm done. I sitll need to tweak the timing a little but the engine seems to be running pretty good now.

Ahh yes. They do spin in a different direction. I thought when you said you have the same setup, you had a Pontiac engine too.. Didn't read the TPI bit.. :oops:

What predictor algorithm are you running? I have noticed my timing jumped around a bit on 1st High 2nd Low, so I changed it to last ...

Okay, I tried the settings for MSD 6A as shown on the megasquirt.info website.

these are my settings:

Ignition Captre: Rising Edge
Cranking Trigger: Trigger Rise
Coil Charge: standard
Spark Output: Normal (going low)

Trigger Offset: 0.00

I reversed my wires , I know have Purple Striped wire on ...

MSTweak won't open my datalogs the way they are formatted from MS-II, is there a way to change what information is exported and the colum names and such?

i noticed removing

MSII Rev 2.30000

from row 1 helps my mstweak

thanks

My table is a combination of MSTweak plus manual tuning. Autotune didn't exist yet. If you can get MSTweak to work with MS-II, I highly recommend it. My setup started with MS-I and a NBO2 and that's what I did my logging/MSTweaking with. Shortly after that, I got my MS-II and a WBO2. I imported my ...

my software settings are exactly as yours, I printed this post.

Input: falling edge
spark out: going high
cranking trigger: trigger rise

i'm going to recheck my wiring tomorrow night, (spent too much time on this today)

a side note on the STOCK MSD wiring

Dizzy: striped orange to MSD Harness ...

I have a TPI motor a Pro Billit dizzy, locked out, I inverted my wires from the dizzy to the MS unit. and set then engine at TDC #1, droppped the dizzy in and the rotor bug pointed dead inline with tower for #1,

when trying to start it ..it acted retarded, so I mssed with tirgger offset, and ...

the MSD ignition rev limiter claims to drop cylindrs, and fire those same ones on the next cycle, to prevent a large build up of fuel, however, on high horse power motors, damage can occure if sitting on the spark cut rev limiter too long.

I saw a guy with a big nitrous fogger stay on the rev ...
