fmic problems

[RXMmazdaspeed]

like grcuadros posted in a thread he created, my car seems to bog down around 4k since installing the hiboost fmic... most noticabley in 3rd, 4th, and 5th. The car's psi jumped from 5-7psi after the install, and i have reset the ecu properly which helped clear up some problems i had initially.

i had blown a couple pipes outta place when i went for the first couple drives, and have since tightened everything very very securely, so im about 95% this isn't the problem.

maybe fuel cut? a few times last night on the highway i was able to get past that plateau at around 4k, but msot of the time it just boggs down really bad. anyone have any suggestions? would getting DSMconvert's AFC help to solve this problem? any suggestions, help, ideas, anything, let me have it.... thanks in advance.

the ecu is freaking out because its seeing too much boost. get a unichip.

[RXMmazdaspeed]

unichip is a little out of my league money wise right now. the afc is, however, within my budget. i planned on getting this later this summer, but will order this earlier if it will help solve the problems.

i'd go with the unichip unless you don't mind hacking up your factory wire harness. I did that with my civic when i installed my greddy turbo kit. The car never ran the same again after it was pulled. The ecu couldn't read the right voltages.

i have th esame problem, sometimes my car runs like a champ sometiomes in runs like a chump, my car is oficiallt Bi-Polar, but im getting a unichip end of summer so i should be good :)

if i could cough up the money for a unichip i would... but im in the process of getting the full turbo back from corksport... then i planned on the afc... can anyone just tell me if the afc would help with these problems?

I'd like to know the same thing, because my car is behaving in the same manner. I'll be able to monitor A/F soon though, once I get my wideband installed. I was thinking of going with AFC or the FTC that DSMConvert is working on.

Anyone know?

Read the reviews, and decide for yourself. Here's one ^^^

Exhaust will definitely help. The amount of boost that the engine is seeing has increased, stock exhaust is restrictive so it might be having problems exhaling, lol. Yes, the afc will help alot. That, along with exhaust should probably clear your problem for the most part.

[RXMmazdaspeed]

good.. im ordering the corksport DP this week, and im in line for teh next batch of corksport exhausts... now if only i could find a used, cheap DSM AFC...

[Yay-Boost]

If your car is bogging since you installed the front mount you probably are not going to help it too much with the AFC. You should already be running leaner than you were before the FMIC! Front mount has a lot more air volume in the system. This is what is causing your bogging. Cat removal (via Corksport exhaust) will help to offset some of the bogging since it will spool up a little faster. FMIC and stock boost isn't the greasest combo. Many people have complained of performance reductions. Higher boost will help the bogging but I'm sure you already know the risks there.

[RXMmazdaspeed]

well the boost went from my stock figure (5psi) up to 7 and holds steady there.. so i know the boost already went up. the downpipe im hoping will help... and i wish i could get the exhaust sooner but i have to wait for the next batch to be done which sucks.

[dirtysouth_msp]

Restriction in exhaust is mostly due to the dual cats and a little to do with the stock muffler. Down pipe may help a little, but probably not that much. At least you will already have your downpipe on when you go to install the exhaust though.

are u flashed or unflashed?

[CChris704]

ken from protege garage is holding a group buy for unichip for 749 shipped, i'd recommend it to the few of you wanting one... one spot left.

im flashed... the problems have gotten better... but theres still stalling in first gear, usually when i rev up when im second in line at a stop sign and the guy in front of me goes... or sometimes in rush hour, but always in first gear.... still about half the time around 4 k in gears 3rd thru 5th im having the hesitation, bogging, whatever you wanna call it. but the other times my car is a beast... i raped a a4 1.8t with exhaust yesterday when my car was running well... then about 2 min after the race my car was weird again, then 2 min later it was fine again. i dont understand it, im not sure if my ecu is still screwing with a/f ratios, or if its the exhaust, or if its a combo of everything. but i believe that after i have my full exhaust and afc my car will be fine.

[mspHtown]

yea hopefully opening the exhaust up and have the a/f controller will fix ur problem.

Keep us updated, so I know what to do to fix mine.

what do you have? and your having the same problems as me?

[RXMmazdaspeed]

what do you have in terms of aftermarket goodies i mean

[livelyjay]

I knew what you meant :) Ion FMIC, Injen CAI, P5 radiator, flashed ECU. It bogs big time under heavy acceleration.

[irr5302]

check the engine coolant temperature

FMIC block air inlet
increase coolant temperature and the computer retard ignition

good luck

I'll do some data logging this week and keep an eye on coolant temps. What are the norms? I bought some water wetter the other day but have yet to put it in.

[RXMmazdaspeed]

well... my corksport DP is sitting at home and im installing it tonight after i go to the gym.... hopefully this will help a little bit. the problems btw have been getting progressively better... most of the time the car pulls rather hard and only sometimes the car gets stuck around the 4k mark. hoping the DP helps a little, and i should have the rest of the exhaust in the next couple of weeks pending me buying it from another member.

It's either the ECU learning, or you are driving around the problem. I noticed when I slip the clutch into place more, or don't shift as fast, the bucking doesn't happen as often.

[irr5302]

The regular Protege run 185oF to 200oF Max 210oF coolant temperature

8 lines in the stock guage 185-200
9 lines in the stock gauge 200-215

probably a combo of the two... i know when i shift hard into 2nd near redline in 1st it bucks horribly.. but if i give it a little extra gas when letting the clutch out its perfect... but the conditions around 4k and up have also been getting better. so id say your right in both aspects.
