gaaaaaaaaabe

So I have a couple questions, I've been doing all the setup work to figure out how I want to make my custom harness to slide a volvo T5 into my 1990 mx5 and I realized that my pnp only has 4 injector drivers exposed (go figure), later in the manual it also says that there are no drivers for inj7 and 8. does that mean that 5 and 6 may possibly exist? I also can't find ignition 5 and 6 anywhere on the pinout either. Is there a feasible way I could run a 5 cylinder on 4 inj and ign pins or should I look at upgrading to a g4x extreme wire-in for the extra outputs?

Well, no lights anywhere, I plugged it into the car just to make sure I wasn't missing anything. It has 12v and still doesn't post. I don't understand how it could just spontaneously fail while the car was warming up, there's no sketchy wiring anywhere ahaha.

So I decided to try out some different timing values today and the car turned on, idled for a while, then I went back outside with my dad to show him that it's working and then the car dies outta nowhere. As funny and as convenient as it was, the car doesn't start anymore, no more fuel pump prime on key on and my laptop no longer detects it. All the appropriate pins receive the correct amount of power, which leads me to believe I have somehow fried it. Where should I start when it comes to diagnosing the ecu out of the car? Or am I better off finding money to buy a new one and hoping my mx5 doesn't eat it.

I gave your recommendations a go and it seems to be a lot happier to start, but it still takes a couple cranks before it decides to pick up. Definitely onto something there, I thank you for your help, I'll keep adjusting to find out what works and I'll probably post an update tomorrow morning if I don't get the car started in the cold. Thanks again

I'm a hefty chunk lost in my tuning adventure as I installed the pnp link g4x into my 1990 1.6L mx5 with 380cc injectors. I got it up and running with a jump start initially and I've been running it ok with my blocked out fuel table. But when it comes to starting of a morning (around 10°C), it just doesn't start, it won't even try and fire. It's only a little bit better when it's a warmer ambient temperature with me being able to start after a couple cranks when the engine is cold. I noticed while logging, that my afr dips down to 10.2 a couple frames after the rpm picks up before going back to stoich, but that's while the engine is somewhat warm, not sure if that's relevant but yeah. I know my tune is probably bad, but I'm tryin' my hardest to learn MX5.pclx
