Is it possible to use an RteK chip on an N350 or N351 ECU for a 6 port turbo engine?

on a n333 i use to use 1.5 with a hi flow fuel pump and raising rate fpr and of course all tii electronics. but you are running higher compression on the s5.
im now running 2.1 same setup and running good.

If you turbo an NA, you should use the turbo ECU, MAP and AFM. The ECU, MAP and AFM must all match. Don't mix NA ECU with turbo MAP/AFM or vice versa.

I'm sorry I should have specified i'm running an 6 port s4 block and internals with s5 turbo and intake manifold. I'm not sure what front cover it is but it has the spot for an oil return flange so it must be a turbo front cover... so it doesnt have the really hi compression s5 rotors just the s4 which I believe are only 9.4:1?

To the second reply I was wondering if I could get an NA ECU chipped by RteK so I didnt have to get all the turbo stuff but I guess I cant.

those rotors are still a higher compression than the turbo rotors of any series. As turbo2ltr stated get the turbo ecu, map, and afm. I am running a 6 port turbo as well and have no had any issues with the Rtek 2.1. I suggest you get that one so you have the ability to make adjustments to the map, both fuel and timing. Otherwise in the end you will more than likely end up regretting it.

just run all s4 eletronics rtek 2.1 s4 ecu ( ialso used a 1.5 for a while with a raising rate fpr, boost sensor, afm , im also running a walbro 255 and 720 pri and 740 sec injectors and im doing this on a 88 6 port so you should be just fine , or if you have s5 car you would the turbo electronics for a s5

I'm doing a 6 port turbo on my S5. Im using a T04B turbo though. Will a N374 with rtek 1.8 work? This is just temporarily until I get an adaptronic. I wont be boosting much maybe 5-7psi external wastegate.
