When I am pressing the gas on the turbo'd civic, the engine seems to bog down between 3500-4000 rpm if I am pressing the throttle less than 50% and then after 4k, it rev's up normally. If I floor it, the car will rev to redline normally without any hesitation. I think my fuel map might not be working well for the turbo. Haven't reset the ecu yet.

Will resetting the ecu resolve my issue? Thanks guys.

 

So - i'm assuming you don't have hondata or anything. You just have a chipped ecu?

Thats too bad if you do. It seems like a fuel problem; however, it could also be an ignition problem.

Did you JUST boost the car?
Did you have the same chip on your car before you went boost?

 

Was just recently boosted. Same chip as before. Didn't have this acceleration problem at first, but now after a couple weeks it arrived. I was planning on upgrading the ECU and then tuning. Bad idea?

 

What's done to the ECU? What's this "chip" have on it?

yeah. Don't use the same chip. I guarantee thats your problem. the fuel maps are completely different.

There's a guy selling a hondata s300 w/everything for like $500. He said its basically new. I say go for that. I have an s300 and its great. You should try it

 

Is it possible to tune with the stock ecu?

Seeing as you mentioned your ECU is chipped... than you can most likely tune off the stock ecu.

HT just tends to like the Pay to play options.... If you are obd1 looking into Crome (www.tunewithcrome.com) if you are obd0 look into TurboEdit.


Give us more info about your setup... injectors? ECU? etc....

 

Maybe I wasn't clear when I wrote my responses. My ECU is not chipped. It's stock. I was wondering if the stock ecu could be tuned? Do I need some sort of EMS to tune or is it not necessary?

 

So you are running a stock ECU with a turbocharger installed? No check valves or FMU?

 

Well thats why. I say get hondata s300.
I also suggest you to not drive the car, if you do, try to stay out of boost.....at least until the car is tuned.

Once my setup is done, i'm having it towed to the place to get it tuned. Not risking anything.

Or if he has a usable ecu (GIVE US MORE INFO ) then he can get it chipped for like 50bucks... and then Tuned... and have a stable setup.

Stock ecu... is just asking for Kaboom.

 

$500 is a bit too much. If an EMS is not necessary, than I won't get it for now. I just want it to run stable. So I am assuming, I can just get my stock ecu chipped and then take it to a shop to tune.

Where can I get my stock ecu chipped?

You STILL haven't told us what ECU it is... what car its for and lots of other stuff. We can't help you with information...

 

I'm sorry.

Its a 1997 Civic LX.

 

Thats me he's talking about.
The hondata s300 i'm selling comes with the p28 ecu already chipped and everything. I think the s300 by itself cost about $500.but thats without socketing and the ecu. I have everything.

 

You need to convert to obd1 and get uberdata or crome. What fuel management are you running as of right now? If you aren't, please stop driving your car.

So wait....

you have a stock civic lx fuel system, and added a turbocharger system?

How is the car still running? DO NOT keep driving it like this!!!!!!!!!

 

Thinking of getting p28 ecu with conversion harness and then getting it professionally tuned. No EMS or FMU. Is this OK?

If you get it tuned, using a chipped ecu... it becomes the EMS... its not a true "standalone", but it does the majority of what is needed.

I'd suggest finding a Crome tuner.

 

Crome tuner? What is this?

 

i dont think any of us are tying to sound mean but you need to stop driving your car. it is not ok put on a turbochager and not add some type of fuel management. trying to boost on a completely stock ecu will destroy your motor quickly. your stock ecu doesnt even know what boost is and has no fuel or ignition maps for boost. so basically when you boost you car is getting way too much timing and not enough fuel. this is a recipe for disaster. so please do not boost at all until you get some engine management. here are your options

1. do nothing and blow you motor within the next day or so.

2. get an FMU and an inline fuel pump

3. **Best Idea** get your ecu chipped and then get someone to tune it with a cheap EMS ex: uberdata or crome

cliff notes: you cant not drive a turbocharged honda on a stock ecu, get an EMS and some tuning asap

 

Thanks guys. Boost is off for now.

Where can I get uberdata or crome? Is this a program I download the the ecu? Or do I have to tune on a dyno as well?

http://www.pgmfi.org , http://www.tunewithcrome.com Its a tuning program that creates a custom map that is then put onto a chip... and then put into the ecu. You'll want to street and/or dyno tune it to get the best results. Or just check http://www.xenocron.com/bins for other peoples files... that might be close to your setup (i personally don't like using other peoples stuff.... get it tuned).

 

Wow this post has been extremely non flamer. You are lucky there "Dan"

I would suggest doing massive searching and reading first. As you read and search you start to see what really needs to be done. One being not to run the car at all from now on until you get it tuned.

You might already have problems internally since you are having bogging problems, unless your ECU is in "limp" mode which might cause this. Just take it easy and search, then make your decisions, or post more questions that you don't understand. Good luck.

 

Just talked to a perfomance shop. They told me I don't need to change by ecu. I just need a boost controller and fuel management unit and then tune it. Sound right?
