GTR ecu vs. GTX ecu.

[ryan1]

Does anyone have any info about the differences between the two?
I.e.different timing or different fuel maps,etc.

[atomicEGT]

fuel maps are for sure different given that they use different injectors

GTR doesn't have boost cut

[FE3-323]

the GTR ecu will net you significantly better MPG - on my 323 it was an average of 6-8 mpg better.

what set-up were you running at that time?

i know the gtr has no fuel/timing cut and was set-up for 440 or 460cc injectors.
Does anyone know if the timing maps are more aggressive or less than the gtx ecu?

I guess what I'm mostly asking is..... I have ran 460cc injectors,na rx-7 vam tuned with a gtx ecu with a small .42/.48 t3 at 18 psi and ran great for years on my AWD protege.
well i have been out of the bg scene for last couple years, even thou i still drive a turboed escort everyday, just working on other projects.
but lets say i run the same set-up as above....
460cc,na rx-7 vam tuned,.42/.48 t3 at 18 psi will i gain anything from running a GTR ecu vs a GTX ecu?

660cc injectors on my FE3 turbo setup.

Yes the GTR ecu is a nice change of pace for all bits of daily driving. the timing maps are more aggressive than the GTX. but not as aggressive as persay the NA ecu(obviously not a good boosted ECU)
