It is what the gauge on the tuner studio is showing me, along with a red gauge. I haven't had a chance to actually put a voltmeter on it, I plan on doing this when I get back. I know it does not make sense which is why I was hoping somebody knew what i did wrong to get a reading on the ...

Don is correct, Not 7.4 AFR, 7.4 volts which IS odd on a 0-5 volt supposed signal. Now you are starting to understand my problem. It doesn't make sense and I am wondering where to look. The gauge in the car responds favorably to changes in the VE table. That is if I lean or fatten up the mixture ...

I am using firmware 2.920. I was running MSI for a while successfully. Just swapped out the 4 pin GM module for a 7 pin, got a newer computer to be able to run tuner studio, bought tuner studio, loaded the firmware for MSII and everything works but the O2. I agree 7.4 is way out which is the nature ...

Yes, I did that. But I see something that I want to try.
Either way, any idea why it won't recognize my NB sensor when I try to switch back and try to use it? Something is telling megasquiirt it is lean (7.4 V on wideband) or zero on narrow band but the dash mounted AFR gauge is showing "good ...

Where is that? I followed the directions on the DIYAutoTune.com web site FAQ's. Is that the same as you are suggesting?
Strange thing is that the narrow band doesn't work either if I hook it up instead of the wideband and change all the settings to NB in tuner studio. Is there somewhere else I ...

Hi, I've just converted from MS1 to MS2. I've installed an innovate mtx wideband sensor too. My problem is that I get no signal to the oxygen sensor gauge in tunes studio. The gauge goes red and says something like 7.4 volts. The meter in the car appears to work OK. If i disconnect the wideband and ...

I am converting from Megasquirt I to Megasquirt II. To control the spark I am removing the 4 pin GM HEI and replacing it with a 7 pin GM HEI, new, probably for a coil in cap distributor. I am planning on using the original style external coil original to this engine. My question is: The original 4 ...
