Ok where should I start. Just to let you know I'm still a learner to MS, so explain yourself so I don't ask newbie questions. I'm running a mspnp base map for 94-95 miata on my ITB MX-3. I have flashed the MS and loaded the map. I changed the wideband settings to innovate. The car idles good, but it has a miss. I did my timing two times and it was correct.
1 problem: I installed an Innovate LC-1 wideband w/analog gauge. The MS will show A/F ratios for a few seconds (like 15.2 and around that area), then drop to numbers like 1.9, 1.7, 1.4, etc... The innovate gauge shows 8 (which is the lowest number on there), but if I barely hold the gas it will go to 10. Without this I cannot tune my car at all! I'm going to test the sensor by spraying carb cleaner onto a rag and putting the sensor in the rag. There is a youtube video about it.
2 problem: Ok here is where I think is messing everything up. I took my spark plugs out, and 1 & 4 are nice and black and 2 & 3 are brand new. Now, I crank them out of the engine and saw that 1 & 4 where really bright and 2 & 3 were not so bright. So I looked at my ignitor and it had corrosion. So I put in a spare one that I had and now It doesn't fire right. (I'm using DSM ignitors and the 1st one I had on there was a 92 style one, and the spare one was from a 94 style which has an extra 2 outputs. One says Vb
and one says Tach) It wont idle unless I would give it some gas. I'm think is my coils that are going bad. I'm going to pick up some extra ones and try it again.
3 problem: So thinking that cylinders 2 & 3 were too clean, I decided to check my injectors. I tried testing the ohms, but I had a hard time holding the voltmeter tips to the small injectors. Then I just hooked up the voltmeter to the injector harness and cranked the engine. I can't remember the numbers but they were way off between cylinder 1 and cylinder 2 (I didn't test the other 2 thinking that was the problem, which it could be). But tomorrow I will compare all of them. I opened the MS and I could not see any signs of damage/burn to anything. I will also look at my solder joints. When I will test them, should I do voltage? What numbers should I be looking at if MS is grounding them? Any other way to test them?
