GTiR NX2000 Swap - running extremely rich!

[VisionRx7]

I just completed a sr20det gtir swap into a nx2000. The car is running so rich that it fouled out the plugs in about 5 mins of idling/driving. I was told to use the stock mafs from the nx2000, but I am doubting that now. The mafs plugged into the gtir wiring harness. Can anyone confirm that the stock nx2000 mafs is the same as the gtir's?

BTW, the engine's electronics are stock, so there is no way for me to tune the fuel in. Also, it looks to have the stock top feed 444cc injectors (yellowish with the JECS A46 00 marking). I know they are low impediance injectors, so the stock resistor pack is wired in.

Thanks for your help,Jesse

Question is what ECU are you using? This will determine what MAF you should use.

the nx2000 maf and the gtir maf is different - nx2000- 53j00, gtir 54C00- what computer are you using? if you're using the gtir computer you cannot use a u.s oxygen sensor,you would have to use the o2 sensor from a gtir or a z31- also get the bung that the o2 screws into
