Nissan 200SX Club - South Africa

CA18det, I got a tdo4h, 76mm exhaust and cone filter.

Goning to put the car on the dyno, what can we adjust to make more power? Air screw? Pick up the boost? Im worried bot injector duty cycle.
Repaired the turbo now so thats y I'm putting it back on the dyno

Before any mods, it did 150hp on the wheels

No point in putting it on dyno because you cannot adjust anything on the stock system.

Whats the air screw for? Cnt you give more timing with boost?

More boost should have less timing. Ive we are talking bout the same screw ,its for idling. If you have an adjustable FPR you can up the fuel pressure which will make a small div.

the std ecu has a base map of 15deg if you change this then the fuel maps will be incorrect causing exces of fuel usage and chance of a knock at your door

best is to leave it at 15 deg i have a t3t4 at 0.75 ajustable fpr and huge intercoler and it funs perfect on 15deg timing

best disconect your batt so the ecu resets then let it adjust for the new settings wont be 100% but it will be better

The guys that have done minor upgrades,
exhaust, intercooler, fuel pump and more boost, should take a look at this.

With current exchange rate it will come to R1300
I did this on my skyline rb20det, I think it was the best bang per buck,
You get cold start, reliability, fuel economy from the std ecu,
but a marked improvement in midrange from the retune.

I put the std afm with untouched air screw, and its leaning out? I put my std afm which the previous owner fuked up and its ok, but its overfueling like crazy, 250km's to a full tank

Nw wats up with that
