New Member help - mspnp bmw vtps idle speed issue
 

Heya guys and gals,
I'm a newbie here, just bought myself a 91 mx5 (miata to my friends stateside, im based in australia) and seeing as this is the forum to be in i had to join to see if someone could help me out.

The car is running a megasquirt mspnp 9093 ecu, 550cc injectors, gt25 turbo, and a bmw e30 VTPS. The problem is all this work was done by the previous owner who had no luck with adjusting idle speed. When warm the car idles at about 1400rpm. I was hopnig to get it back down to around 1000rpm, close to the factory 950. Thought it might be the vtps so went into megatune to check callobration. closed it read 1adc and WOT it read 8ADC. These are much lower than what i expected???

I'm new to megasquirt so know very little about tuning it but here are the dump screens from the idle setrting.

Any help for a novice would be appreciated.

Thanks

Justin
