hello guys maybe this has been talk over already but i have not been able to find good info. so my question is if i buy a n374 and do a rteck chip upgrade will this correct the problem with not firing the secondary injector or only the knightsport chip will ?please any help will be appreciated thank you in advance guys

 

Any body please I need help ASAP thank you

 

I'm an s4 guy,but If I recall right in my reading the N374 is a Jdm ECU and it has had problems running a USDM engine.
have you looked into a N370?
Mike @ Pocketlogger may be able to help you with questions too.
He actually Phoned me in Canada when I had problems with my Rtek 2.0 Install on my S4 TII build,so the Customer service of Pocketlogger is real good in my books.

 

Thank you for the info. I have look into a n370 but have not been able to find one at a decent price so here is the second question.
My engine is a s5 jdm running a s4 na modified harness with a n318 Ecu if I get a n374 ecu and jdm harness it should work right because according to my reading there an issue in the usdm harness if I recall correctly anybody has more info on this I will really appreciate it. Since is the only thing stoping my build thank you in advance

 

Ok..
I got(well had,I am haltech now,and more modified) an S5 TII engine in my 86 NA.
I used the S4 N/A harness.
I used the s4 TII injectors,N333 ECU,N318 boost sensor and N318 AFM.
I kept the S5 Turbo.
Used the S4 Front cover and waterpump housing,waterpump...had clutch fan,went E fan.
S4 TII sensors.
