I've had my MS3-powered Seven going for a while now; it's my DD unless it's raining or snowing. However, I can never really put it to the limit, because sometimes, when I go to WOT, it'll pop, like a backfire, and lose power for a beat, then go on as if nothing happened. I'm thinking it's running lean when it does that, but no matter what it is, I know it isn't good for it. So I typically keep everything at about 50%, and it's fine, but it'd be nice to really be able to beat on it.
I know I need two things; I need a wideband controller, and a good dyno tune. Sadly, both things require money, and I have none of that either. I have the wideband sensor, but no controller yet. It's high on my list. I've heard of a dyno shop in the area, but I don't know if they have ever dealt with Megasquirts before. What I really need is someone that knows the MS3 really well.
I'm using a 1994 harness, fuel rail, and ECU. The engine is a 96. I have no accessories, only the alternator. I have 550cc injectors, a Walbro 255lph fuel pump, a Super16G turbo, Nissan (I'm guessing) SR20DET intercooler and BOV, and I've converted from MAF to MAP. I'm maxing out at 10psi, for safety's sake.
Here's my data. I couldn't upload anything other than the MSQ. All the datalogs are in this drive due to size.
I've had it misfire/backfire, whatever that is, in several of the logs. My fuel map seems a little lacking towards the end. Am I missing something? I've used VE live numerous times, and this is what it always gives me. Perhaps a similar Miata tune would help, maybe one using a Disco Potato?
