Hi everyone,

I am learning how to tune my 99 Miata through tuner studios while running MSPNP2. My main question right now is what can be causing my VE to be 105 at idle. I am just starting to get it to idle. The base timing is set but I still have it in fixed timing. Havent not changed to use table. Right now its idling well at 1300 rpm but my VE is at 105 to have an AFR at 13.5. My tune is attached and I ran a log as well. I cant seem to figure out what the issue could be. I have attached my tune and the most recent log. Any help wound be greatly appreciated.

Parts in the car:
wisco 10.5:1 pistons
Engine was machined and bored to 83.5mm
converted to returning fuel pressure system sitting at about 60psi
DW Injector 18U-XX-1000-X injector spec sheet attached
skunk 2 intake and 64mm throttle body
It has a turbo
GM IAT sensor
Added alternator controller to MS to maintain 14v
AEM O2 sensor

 

I'd confirm two things. One, make sure the part numbers on the DW injectors match what you bought. If you have 700cc injectors and think they're 1153s, that'll cause your issue. Same with fuel pressure, check it and make sure you're at 58psi.

I'd change it to "include afr" in fuel calc, but I don't think that'll fix your issue. Later, if you change your target, it won't require as much of a re-tune.

If fuel pressure is good and injectors match, I'd be contacting DW.
