no. It's possible you'd want to remove r57, but that's something to ask DIY.

Worse comes to worse, I could tell you how to mod the opto-isolator circuit to be invertered, but the VR should work. I use on all my 90-05 builds.

Well I put the stock ecu and MAF sensor back in to try and start it to burn the extra gas again and charge the battery back up. The car would Not start. I checked everything and reset the stock ecu and it appears some how my coil packs are fried. Each time I updated the firmware I un plugged the coil so I dont know how in the heck they fried. I surely dont think the MS could have fried them. I am interested in going cop put really dont want to mess with wiring them up for my car. **** this freakin sucks.

it's probable that your MS1 MSQ the spark output is set to normal and the MS2 MSQ it's set to inverted, or vice versa. This will fry coils. That's why you gotta be stupid extra careful when burning random maps, as your MSPNP, even with the ms2, shares little in common with a DIYPNP.

Yep thats probably what happened to me. So the msq that is on diy site says (Going High) inverted is this correct for my type of build. I did switch it one time to (Going Low) Normal because I thought it might have been the reason for my no start. Either way I fried the suckers cause i am getting a code 1 CEL on the stock ecu. I just dont want to buy replacements and fry them again. Too expensive to replace. I wish I knew some one that could sell me a set of COP already wired for a 94. I looked over the instructions posted briefly but I am afraid Ill f up. I replaced stock coils before on the 91 I had so I know I could do that but 94/95 like oem coils are ridiculously over priced. The COP kit on Trackspeed is expensive too. Either way I will need new coils just dont want to burn through another set with the wrong ignition settings.

Find a used set. I sold three stock coils from a 90-93 for $30 each set.

Hey Brain so I decided to go ahead and upgrade to COP, I figure with how cheap they are to replace in the long run they will out live the rare 94 to early 95 factory coils. I was reading your diy and it looks pretty straight forward. Do you think you may be able to help me with a proper base map. I understand the dwell settings for the COP my main concern is that I dont fry the COP from the wrong spark output settings for my specific ECU. I could send you some beer money or something for all your help.

So I got a used coil from a member on here and it work fine on the stock ecu. I confirmed my base tune with Matt and still no crank signal.

Did you ever get this working? I've got a gen 1 mspnp that I'm thinking about upgrading to ms2 as I have a spare daughter board sitting here, but the car runs well on the old Motorola processor.
I'd hate to fall into the same trap and fry my 94's coils.....again. Not cheap!

Don't do it I ended up sending mine to diyautotune and they still couldn't upgrade it. Not worth the hassle just keep ms1 or sell it and upgrade to ms2. The only way to upgrade is with a diypnp. At least that's what diyautotune led me to believe.

Man that sucks, oh well

Sorry you had to be the guinea pig for this but at least it will help others out.

So I take it you went with a diypnp route using MS2?

Yep best decision ever made. Honestly I would never buy a MSPNP enver again. 1) it cost more 2) I like being able to easily modify the board. 3) Brain helped me out a lot with the v1.5b board all of his write ups for the most part apply to that board or the 3.0. 4) Surface mount parts are a major pain.

I definitely agree about the ease for expansion on the DIY units vs the pnp.

Having built several 2.2 ms1's and a couple of ms3's I can relate to that. The only reason I ended up with this mspnp is the fact that I got it just before the mspnp2's came out and it had a dying mapdaddy on it. So $250 bucks and a spare sensor from a previous 2.2 ms1 later I had a cheap standalone.
Just a shame it is limited, but then again so is my clutch currently
