Am I missing something

[Per J]

I´m about to go on the dyno , so just wanted to make sure everything was ok.
Car is a bmw m20b20 with added turbocharger. Engine is completely stock apart from bigger injectors. Running 12 psi and so far no knock has been detected.
( MS2 extra in shape of MSPNP Generation 1 from DIY running current firmware)

I´m actually quite surprised the d*** thing hasn´t exploded yet. But it´s running like charm. A good wideband can get you a long way it seems

Anyway let me know if anything looks odd

your fuel ve table only goes to 150 on the load, I suggest you increase to 50kpa over your normal boost level atleast, say 250kpa
Your datalog already shows you are going up to 180+kpa as well
Also I suggest a TPS and how big is the turbo?

Thanks for the reply

I completely forgot about the Kpa scale thanks for the reminder

The turbo is a Garrett GT 2860 Rs ball bearing with a built in wastegate
Compressor turbine is 60 mm and exhaust turbine is 54 mm
A/R is 0.86

I´ve been thinking about adding a real TPS aswell , since i´ve had some trouble with the Accel Enrich. It´s kinda hard to make it cooperate with map only.

My friend has a 2.7l m20 e30 with a GT2876R. With a TPS its a lot better.
Also I think the AFR target table takes a lot of fuel out, when your outside of boost. to much imo.

I´ll give it a go , been having a bit of lean surge in those areas.. Will try to add some fuel.

2.7 is a great engine. Is he using the stock head or the 885 head ?

2.7l bottom end, 2.5l head, forged supra rods, supra pistons.
