bigger turbo = more CFM & possibly higher boost = dumping even MORE fuelEscort GTR -- 11.87 @ 117.6 mph -- 320 HP / 325 Ft. Lbs. @ 23 PSI

i dont think your finshed .....
i dont think your finshed ..... so what since theres a bigger turbo,,, the ecu can tell the diffrence even thoght im set at 10 lbs ... so i have to reduce the fmu..or should i play around with the waste gate ..cause i mean its wierd .....starts up holds idol ... go out on the highway, i cant even make it out of 1 gear with out it bogging some where around 3500.. but like insane ley ,,,crazy......i think my o2 is fuked due to oil spillage that ihad last month from the turbo ......like open throttle im rich ./... now it depends on how i step on the gas i start getting lean readings .....

welllllllll... your engine management sounds jerry-rigged at best, sooooo i think thats probably your main problem. combining bigger injectors with an FMU and a safc on a stock ECU is going to be a practically un-tuneable nightmare.
and yes a larger turbo flows more air at the same boost. the ecu doesnt read boost, it reads airflow.Escort GTR -- 11.87 @ 117.6 mph -- 320 HP / 325 Ft. Lbs. @ 23 PSI

a GTX ecu... and if you are hitting boost cut, get some 460cc rx7 injectors and tune with the safc and a MAP sensor.Escort GTR -- 11.87 @ 117.6 mph -- 320 HP / 325 Ft. Lbs. @ 23 PSI

I had a 14b on me pro with 440 cc injectors an fmu and the safc, I used to fowl out plugs and start bogging between 3000 and 4000 rpm. I call the local dyno tuner, he called me a fool for using a fmu with 440 cc injectors and an safc and not expecting to drown the engine (harsh words werent they), I took off the fmu and ran fine. But make sure you get dyno tune soon.Originally posted by Lil Freeksome people just need to get laid... with a woman, man, goat.. whatever.. just get that tension out into someone/something else

FMU's are made for running low boost (5-6psi) with your stock injectorsEscort GTR -- 11.87 @ 117.6 mph -- 320 HP / 325 Ft. Lbs. @ 23 PSI

now explain this ..
iight so if you read the subject in hand you already know what was my problem this mourning ....
so i had to go back out to pick up the lil lady from work ......i useually run 93 octane since i was empty ... and im running to rich i figure let me see if ican lean out the car a lil with midgrade fuel 89......car ran like **** after i gased up ..like while in gear anything above 3000rpm would bog out like crazy.. so to make a
long story short ... wene i got to where i was going ,,,,... i re adj. the tps screw ..brought my idle ,.,to like 1350.....then i reset the ecu ,,, and she started runinng good again ,... can any one confirm if it was the fuel change .. or the tps the maid her run smooth

Ditch the FMU totally. I had one on my old car. I hated the thing. Un-tunable piece of crap.
Keep those injectors you have. They will do for the time being.
Grab a 'GTX' BP26 ECU or a 'TX3' BP58 ECU(rewire pins in plug accordingly). Add in a SAFC-II for finer tunability beyond stock ECU parameters. Add the MAP sensor mod if you want to be more precise.....but just running the signal for the SAFC off the TPS will make it RUN.
Do all that for a start. That should get you back to being reliable
Get a Wideband O2 meter too. They are a required item for doing any home tuning these days. There are a few out there now that have a Narrowband simulation mode so you can just replace your stock 02 sensor and still have the proper narrowband 0v-1volt reading.
*NOTE: Running rich will KILL an 02 sensor. So do the basic above mods first before you foul up a wideband.
Recap:
Lose FMU
Keep 330cc injectors
Add GTX BP26 ECU (w/ ECU pin plug swap)
That will get you "Running"
==================================
Add SAFC-II
Add Wideband 02 sensor/meter
That will let you fine tune and adjust settings
==================================
Swap to 460cc Injectors
Add Manual Boost controller
MAP sensor mod for SAFC-II
That will get you into higher boost levels safely after all of the above are already done.Last edited by Skuce; 10-02-2007, 09:34 PM.Drew
