New Ecu Or Neo Good Enough?

[Draconis]

Okay... So I'm prepping for my power upgrade on my RB20DET.

I was told by my tech. to not go above 50% of the stock injectors. Reason being, the AFC Neo can only down tune the injectors by 50%. I want to get the 555cc Nismo injectors from Slide. If I was to use the Neo to tune it all the way down 50%, then I should only be above my stock injectors by 50%... is that ok? I'll also be getting the Splitfire coilpacks from Slide too. For the turbo I'll be putting on a GT3071R. I am looking for 300hp to the rear wheels.

Can I just use the Neo to tune the engine/injectors along with my Greddy Type S boost controller with my stock ECU... Or should I get another ECU that has been chipped/tuned? I know there are some really good Australian companies that make ECUs for the RB20DET... and if you do advise to get a better ECU than stock, which company do you advise me to go to that's in Australia. Or should I use a non-stock ECU in conjunction with the NEO and boost controller?

I'm in the US by the way and I have gone to several shops around for info on the Rb20 and the best way to do it and get different answers that in just about no way match another in the slightest. So this is why I go to you Aussies cause you guys know your shit compared to the US who all seem to not really care anything beyond a sale.

errm, the Neo doesnt directly control injectors.... it purely adjusts airflow, which in turn adjusts injectors, but the amount of fuel injected is also effected by other things..

your best bet is to save up till you can do all your upgrades you plan on doing then get your stock ECU remapped and use the NEO to do any minor fine tuning.
