i have a few aftermarket ecus here,
i also have a wide band o2 sensor meter.
i am capable of setting up and road tuning the ecus that i have.
i have been down that path b4 and not real interested in it as it will snow ball into bigger things im not interested in.
more power
better pistons
head gaskets
cams
30psi boost
t04z
nitrous
all of which i have
bla bla bla, been there done that, not my thing anymore.

id rather look at the rocks ahead, not the laptop for injector or timing values.

interesting, thanks JR

ill keep reading but was happy when i saw this


That is correct.... I am running 7 psi with the stock computer, stock, wiring, stock injectors, & stock fuel system and ran it that way for the first few weeks with no issues. All I did at that time was to adjust the timing. I installed an AEM UEGO to meter the Air Fuel Ratio (AFR) and saw that it was leaning out at above 6 psi so I added the Rising Rate Fuel Pressure Regulator (RRFPR) for added protection. This made it run a little rich and instead of lean so it was safer at higher boost.

So yes, the stock motor and components can safely handle 5-6 PSI with no issues and I ran it really hard even before I installed the RRPFR and the AFR meter.

Personally, I dont see a problem with doing all that

I ran mine stock set up turbo for no longer then a week. Its AFRs were no way safe. So I'm using standard ecu, jaycar airflow/fuel modifier, $67. jaycar hand controller, $65. Mitsubishi 2.2L galant injectors which are 275cc, and my AFRs are now safe at 7psi. And I have 180nm torque on 31s at 4000rpm and 111rwhp with no gearing. I've fitted 5.12s now and its a weapon. So it can be done. But you do need a IC.

But you ran stock everything and not even a rising rate fuel reg. I believe you were also told to expect these AFR issues straight away

Seem like you have got it sorted now tho

Yeah it was quite undrivable until I done all the mods. It runs awesome now. And running a small turbo, the torque is good. It around t23 size.
