Quoted straight from R-Tek's website.

"550cc secondaries are stock so no change has been made to the fuel map in version 1.5. For version 1.7, the fuel map has been corrected to compensate for larger 720cc secondary injectors without the need for external fuel control, like an AFC, to keep from running very rich. If you have an AFC, it will no longer have to trick the ECU to compensate for the larger injectors. The AFC can be used for fine tuning. This also means that you CANNOT run version 1.7 in a car with 550cc secondaries or you will run lean. Likewise, version 1.8 is expecting at least 720cc injectors for both the primary and secondaries. Injectors with any less flow will run lean and can lead to engine damage. It is OK to run larger that the minimum injector size, but be aware that you will need some sort of fuel control to keep them from running very rich, or move to an Rtek7 Stage 2 ECU upgrade."

But I'm a dumbass that doesn't know what I'm talking about. Some people need to know what they're talking about before jumping someones ass, and calling them names. If you have any questions or want to know the TRUE info from R-Tek, just get the info straight from their website. http://www.pocketlogger.com/index.ph...4T2#secinjsize

Enough said.

wow

Rtek ecu
 

Great way to articulate your statement ! Nothing but hard facts. :icon_tup:

it sure got quiet

chirp chirp

It's funny how some people think they know what they are talking about, and are quick to act like a child and start spouting of a bunch of nonsense. Calling people names like this is highschool. If you don't know the facts, go straight to the source to find out. Do I need to say anything more?

my 1.7 and 750 s should be here fri. the 6th. my birthday btw.i cant wait to get it back to gather. i ll be in touch :}10mm

Another satisfied RX7 owner! :)

nice man.. what you think shes layin down?

That is wrong, wrong wrong. In fact this whole thread is full or fail, reading comprehension fail specifically. Why would RTEK adjust the fuel map to run bigger injectors, and then nullify that work to make it "flow the same as stock?"



You should read this, preferrably a few times, also from the same website you posted:

for anyone with any questions about the RTEK chip upgrades for the turbo FC3S, please follow this link, and be sure to click the "details" tabs for each of the functions listed, and read about the product some more. If you still have questions, then call the number on the website and ask any of the tech support people about the product.

EDIT: for people looking to make some extra power, this is a very reasonable guide to follow as far as tuning the FC:
