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. I think my fuel map might not be working well for the turbo.

How do I reset the ecu? Will resetting the ecu resolve me issue? Thanks guys.

Timmay

doubt it will help you, sounds like you need tuning bad

if you want to reset it , pull the negative off the battery or the hazard fuse in the under hood fuse box

Dan_the_MaN

I'll post my problem in the FI forum as well.

Do you have any kind of engine management? If not STOP BOOSTING RIGHT NOW AND GET IT TUNED.

But yes, you can reset your ECU by pulling the backup fuse under your hood for a minute or two. That's the correct way to do it instead of pulling the battery cable.

I have not tuned yet because I still have my stock ecu and lack of money. Can I tune on my stock ecu or do I have to upgrade my ecu to get it tuned? Do I need to get engine management in order to tune? If so, what basic engine management is out there? I have seen hondata stuff for $1300, but I can't afford that. And I don't really know what it does. Someone help!

Jesus....

Why do people toss FI setups on cars without any knowledge about what they're doing? Did you not realize that your stock ECU wasn't going to cut it? First of all, your MAP sensor isn't designed to see boost. It'll send it into limp mode the first time you see boost. Also, did you not realize that your stock ECU wasn't designed to compensate for the extra air being thrown into your motor, and can't keep the A/F anywhere near safe?

You NEED something to tune with, even if it's as shitty as an AFC or a FMU. You can't just slap a turbo on a stock motor and think that it's going to run well or run for very long.

EDIT: If you can't afford 1300 for some Hondata, maybe you shouldn't be running a turbo setup.

Sorry if I offended anyone. This car is more of a project car for me, I have a G35 I use as a daily driver and am in the process of supercharging that one. Superchargers are much simpler to understand, basically plug and play, so I thought it would be similar. I already over spent my budget to do this setup, so I'm trying to get it right, but slowly. I am a NOOB and I am sorry in advance. If it's any consolation, I got it installed right without cutting corners. I have been driving it on and off for the past couple weeks without a problem.

Here is the setup:
1997 Civic LX 5-spd (tranny swapped with 96 Civic)
Stock motor with 10x,xxx miles
IHI Turbo (this is a moderately small turbo - 1.5" outlet)
Spearco Intercooler
Custom IC aluminum piping (2")
DSM BOV (not sure what year)
New Silicone hoses w/ t-bolts everywhere (550F degree rated)
Greddy Turbo Timer
APEX-i AVCR
New Injectors (don't know what kind - mechanic recommended them)
Custom headers
Stock Intake Manifold - No aftermarket like I see everyone having

QUESTIONS:

1) The only thing I am unsure of is if I have a wastegate. My friend said that I had to have one because the car runs fine. He says its connected to the rear of the turbo and usually comes stock with the turbo. Is he right?

2) I have been using the AVCR to set boost. It's set low (5-7 psi) and set start boost at 3200 rpms. Is this doing anything? Now I am not sure. The boost comes on shortly after 3k rpms.

3) What do I need to tune? Do I need to get a new ECU or some kind of management or both? After getting one or all of these, I need to go to a tuner, I know that much.

4) Any other advice?

THANKS GUYS IN ADVANCE. Without your criticism and input I would be lost. I love this forum.

You need to know the flow rate on your injectors. You probally came stock with 240cc units, and just throwing in bigger injectors isn't the answer.
Also, you don't have custom headers. You may have a custom turbo manifold, which I doubt, but you can't run "headers" on a car with one exhaust bank, nor can you run them on a car that you have turbocharged.

You have to have a wastegate. Without pictures of your setup I can't tell you wether you have an internal wasteage (similar to the Greddy kit's setup) or you need an external (looks similar to a BOV) on your turbo manifold.

I'm not familiar with the AVCR, but can you not use this to change fuel maps?

You need to tune your fuel maps, your fuel trim, and your timing/igniton maps.

You can squeak by with just doing the fuel maps, but I don't recommend it.
A few low budget costs around here are the AFC hack (which I'm not very fond of because of the timing issues it creates) an FMU (which is just a raising rate fuel pressure regulator, and I don't like because of it's lack of tunability) and then there are other options such as E-Manage (which I run, and it's so-so) and Hondata (which you have to convert to OBDI to use) which piggyback on your ECU so to speak. Then there's the option of a full standalone such as an AEM EMS, which is way beyond what you want to do.

Other advice? Stop driving any FI vehicle (or keep it completely out of boost) until you have your engine manangment problems fixed.

Stop turning wrenches, take some time out here, head on over to the FI forum and read read read. Also, a book by Corky Bell titled "Maximum Boost" may be a good thing for you to pick up.

You didn't offend me. I'm just curious as to why you thought you could toss on a turbo and call it a day?

EDIT: And don't just slap a SC on that G35 and call it a day either. You DO need engine managment if you modify the amount of air and fuel being pumped into an engine.

Dude.......lack of money.....and you dont buy the MOST IMPORTANT PIECE OF ANY FI SETUP? No you cannot tune with a OBD2A ECU ( there is some talk about it on pgmfi.org but not worth it to me). Yes you need to tune your setup. You cant just slap a turbo on a car and drive. You can get fuel management for around $300 minus tuning.

$120 for a chipped p28
$75 for bruning/datalogging hardware
$70 for a conversion harness (OBD2A - OBD1)

Then you would need tuning. If you do it yourself add another 300 or so for a wideband oxygen sensor. And if you are going to do it yourself, it would be wise to invest in a laptop

Dan_the_MaN

About the G35, yes I am tuning it after the install. The kit comes with SS piggy back, FMU, and fuel pump.

I got headers and manifold mixed up, you are right. Boost will be off until I get tuned.
I was thinking of getting a chipped ecu and then going to get it professionally tuned. I think this is the bare minimum to run a decent setup. So, I am going to have to buy a chipped p28 and conversion harness? Are there other chips out there? Where can I get these from?

Ricey McRicerton

You can get a chipped P28, a conversion harness, and tune it with Chrome or Uberdata for free if you can find someone with a burner for the chips.

Dan_the_MaN

So I wouldn't need to take it to a tuner? What do you mean by burner? Put the chrome or uberdata program into the ecu?

Yes you would need to take it to a tuner or do it yourself although I HIGHLY discourage that.

A burner "burns" programs much like a CDR drive does except you burn chips instead of cd's. The willem site I posted below will shjow you exactly what the burner looks like, what it does, how much it cost, etc. Once the chip is burned with the program you choose (ie uberdata, chrome ,etc) you place the chip inside your ecu in what is called a ZIF socket which must be soldered to the ECU. You can find good deals on here and http://www.homemadeturbo.com with people who will either chip an ECU you supply, or send you one of theirs they already chipped and most times you can get a basemap.

this guy posted over in the FI forum and i think we have him on the right track. kinda annoying/amazing how confused he is on the whole subject. im not expert but i did take the time to research before installing my setup.

avc-r is just a boost controller.

I wasnt trying to be an *** but you see it all the time. People think you can just put a turbo kit on a car and expect it to run flawlessly. I did give him some advice and wasnt trying to flame....it is just frustrating
