First post MT.net and this is stressful lol..
For the past few weeks I've been reading a lot on MT.net about MS and all the turbo stuff. I thought I would be able to fix my issue only by reading but It looks I'm missing something.
I got myself a custom turbo kit with a DIYPNP. As suggested by MT, I installed my DIYPNP without the turbo so I could learn and tune my MS properly.
Whats installed in the car (Miata 1990 1.6L N/A) :
- GM IAT
- AEM UEGO
- TPS unplugged (VTPS soon to be installed)
My main issues are with the startup/idle.
So here's the problem :
After 4-5 cranks, the engine starts. It goes up to 1600rpm, tries to idle at 1200rpm and half a second later, dies.
I have to help the car to start by pressing a little bit on the gaz pedal. Once it reaches 2000rpm it will idle between 1100 and 800rpm depending if its a cold start or not.
Once the car has started and reached normal temp it will idle around 1000-1100rpm and runs like a charm.
I don't have A/C or P/S and I use PWM Warmup has idle algorithm.
I think I may also have a problem with the IAC. I can't get the car to idle like I want by turnin the IAC. I think it has no impact since I'm using PWM idle, am I right?
I read and played around all idle/cranking settings with no result.
I attached a log file and my tune.
