Hi all,
I bought this GST a couple months ago and I've been fixing many things on it.
Now that I put it all together I got a laptop and installed TunerStudio, I can see the gauges and all.
The smell of gasoline on the exhaust is very heavy. I checked the Engine constants and noticed it is some how running with an engine cc of 5375cc and injectors of 430cc. This makes the (external) ECU calculate the fuel as 12.8

But if I put the right info like 2000cc and 450cc injectors it can not even Idle.

Looking for a base maps made for this car so I can load it and check how it goes.


Running on MAP speed density, no MAF, stand alone coils, 16g turbo, 450cc injectors.

this is for a 1G but might have some useful info for you.

 
If im not mistaken, like the linked post has for semi sequential/batch injection squirts per cycle should be 2, or at least 2 (im not a tuner and that'll be specific to your setup). then required fuel calculator reran as part of its math is squirts per cycle.
I'm still learning myself though, been lurking and doing research for the last few years while working on getting my own running on a speeduino.
