i know this has been asked a thousand times but i couldnt find it. i tried searching it but it did not come up .if some would just link me to the premix ratio tread that would be great.
whats the best ecu that eliminates the omp?
is a rtek stage 2 ecu worth the money on my 91 na?
what suporting mods do i need all i have now is a ext. system dyno max catback and no cat set up from the header to the cat back.
(wtb power window switch rtex ecu and omp)

 

1 oz per gallon for premix, as far as ECUs go any standalone will eliminate it. I am not horribly versed on the RTEK,does it remove that functionality?

 

RTEK does it all and is your best buy. Do it.

It eliminates fuel cut , you can adjust the duty cycle of the injectors (not that lame SAFC adjusting airflow signal), control timing on the Lead or Trail, eliminates any and ALL hesitations when the secondarys come online, logs rpm, timing, boost and any other thing you want. Eliminates the MOP if you want to mix oil in your gas. Just go to the Digital Tuning site or read the RTEK forum or whatever you wanna do. It's plug and play until you make adjustments to it.

EDIT: Oh. You have a non turbo. I believe there is a thread on the RTEK forum where the fellow tuned his series five non turbo and had good results.
