*I've posted this on the HONDATA forum, but I'm trying my luck to see if anyone on HT has the skills to solve my problem.*

I've been having this problem w/ my car where all of a sudden my car surges and my rpm's go up and down while the check engine light turns on and off. It's quite hard to explain, but it happens mainly when I try to start the car and it has also happened in one occasion when I was on the freeway. Then my cars dies. I've had the car tuned before by a reputable tuner around the southern california area so I believe that it's not a tuning problem. Or could it? I was wondering if anyone in this forum has ever encountered a problem similiar to this or can direct me towards some type of solution to my problem? Thank you very much.

My Setup
92 SI Hatch
D16Z6
HONDATA 200B
Greddy TD04 15g Turbo Kit
Jonnyracecar FMIC
DSM 450 cc Injectors
CRX Resistor Box
Greddy Turbo Timer
Greddy Boost Controller

Any help with this from HONDATA pros would be gladly appreciated. I've been out of my car for a good 2.5 months already and it's being a pain in the ***.

Any HONDATA experts want to give me their .02?

FredoSP

sounds like a tuning issue or maybe a VAC leak, check all your vac connections, make sure they are tight - use zip ties.

Did you pull the CEL code? What code is it?

Secondly, if you can, find someone that has the Hondata ROM editor and post your MAPS, maybe some can give them a quick look over.

Hope this helps.

I'm going to check that later this afternoon after work and see if that's the problem. *Crossing Fingers*

I would be afraid of this. I'm not too sure anyone around my town has that capability or knowledge or I just don't know the right people. Everythings about an hour or so away from me (Currently living in Santa Barbara, but originally from LA.), but I'm going to find out through some shop to see if they can help w/ anything. Thanks for the help. Any more suggestions? I've also done some research and heard that it could be something w/ the ignition?

Bump to get the hatch up and running.

Anymore suggestions from any FI experts, before I go home and troubleshoot the VAC lines this afternoon?

Damn, wasn't the vacuum lines. No one's ever run into this similiar situation before huh? I'm going to give it a couple more bumps before I take it to the shop. Guess there's no other solution.

Bump.

I just experienced this same problem in my d16a6/y8 mini me with turbo last night. It was hesitating bad, so I pulled off the highway, @ the off ramp, I was waiting for the light, hit the gas and BOOM died out. I had to coast it into the gas station @ the bottom of the hill. I let it sit for 5 minutes & checked the ecu. I got a CEL #1. O2 sensor. I pulled my hazard fuse, reset the ecu & it helped . No code & it ran until I got home. Still it was hesitating, but not as bad.

then my dumbass tried taking it to work this mornning, died on me twice
So I guess I'm tryin to tell ya it may be the O2 sensor.

ladysman

This is interesting because this just happened to me as well. I get #1 CEL O2 sensor. However, this error ONLY comes on when I DON'T have my laptop hooked to the blue box. I usually have my laptop hooked up so no big deal but most don't have this luxury. WTF?

Spunkster

sounds like either a problem with the injectors (DSM injectors ar enot recommended to be used with a Honda ecu) or an intermittent wiring problem.

Stock injectors for me and have had hondata for 2 years and it just now started. Who knows. Only when I DON'T have the laptop connected!!!

rickske

Now I'm feeling the love! Thanks for all the replies guys. Well first off I had a friend come over (Props to "pornstarSR") to come and check out what's up w/ the setup since he knows more about turbos than I do, but we couldn't fix it! Daaaamn.

We tried getting the CEL code from the check engine light, but no luck in that. For some reason the check engine light wasn't blinking and everything was being reseted(?). Are there other ways to check for the code? I'm assuming through a laptop, but I don't know anyone who has one w/ HONDATA software around town. I'll have to call up HONDATA or somebody for help on that.

I'll try to install a new 02 sensor to see if that's the problem *crossing fingers* and keep you updated to see if that's the problem. Did you actually end up having to replace the 02 sensor?

I've been reading up on forums and what not and I read that the solution to this problem was to have it on either open or closed loop? I'm not too knowledgable in this area so I don't know if this is correct or not. But it can't be an injector problem because my car was running just fine before. Let me try to explain a brief history of what has happened so far. (Story's shrunken down to cliff note format.)

- Bought Turbo Kit and ran car fine for about 2 weeks then idle surges start occuring, etc.
- Unplugged ECU and somehow it reset and car ran fine for a day. Enough to go down south and get it tuned.
- Car gets tuned (from new basemap) and runs fine for about 2 months, but needs to go back to tuner because clutch was slipping.
- Get new clutch and goes back for 2nd tuning session (retunes on existing basemap). Car runs fine for about 1.5 weeks and idle surges yet again!
- Car had to get towed and parked onto the street. 2nd day it was parked I GET JACKED!
- Thieves take my HONDATA, Radio, Turbo Timer, and Boost Controller.
- 2 Months later I get insurance money and buy parts back.
- Plug ECU directly towards the new HONDATA and car runs fine. Gets car washed w/ friend.
- Next morning wake up to go to work @ 8am............Guess what? Idle surges. That's WEAK!!
- Now I'm here trying to figure out WTF is wrong. I'ts been like this everytime I try to unplug the ECU hoping that it will reset something. I'm willing to bring the car out to the tuner and pay for another tuning session, but the closest one from Santa Barbara is like 2 hours away so I need to get that **** towed.

I was told that maybe the chip has gone bad so I'm going to see if I can get a new burned chip from the tuner sent out to me. Any more additional comments. Thanks for all the replies so far.

for HT!

Bump.

I have the idle surge also & I just changed my O2, reset the ecu and and changed to colder plugs, no dice, no codes. I'm in the same boat too.

Spunkster

if it's surging at idle take it back to the tuner...they need to adjust the idle control settings in the ecu.

Good idea, but the distance from where I'm residing at is limiting me to get my car towed to the tuner so I'm using this as the last option, but one thing I don't understand is why did the car work just fine before? Wouldn't you think that I would have had the idle surging problem the whole time I've been driving my car and not all of a sudden? I'm going to troubleshoot this in 2 more ways before I just go back to stock. I'm going to see if its the 02 sensor or my chip got fried. I'm going to have to see. I'll keep you guys updated. Bump for a solution to my problem.

NVturbo

I feel you man...my setup rite now is doing the same damn thing. It's bugging the **** out of me too. I just hate to drive boggin for 1 1/2 hours to my tuner shop, but if I don't get any results soon, this may be the case.

Damn, I thought that I was the only one! Yah I'd hate to go drive to a tuner going about 30-40mph max. So do any of you guys think that this can be a HONDATA manufacturing issue? It's just too damn strange. BUMP for a solution to this ****. I need to find out what's going on. Come on FI specialists! I'm in the process of getting my 02 Sensor switched and New Chipped burned to see if it will resolve the issue. During the meantime I want to see what you guys did to get it to work!

Akiraboy

jus me but I think its a map related error. I think I'm experiencing the same prob, thing is i'm not runnin hondata, I'm using a missing link. Boost and BOG, I have to feather the gas pedal to get somewhere It was boostin great before , weird. I'm not gettin any codes, I went to colder plugs & put in new O2, this sux.

Troubleshoot #1 - 3 Bar Map Sensor

So I unplugged the 3 bar map sensor and wired it back up to the stock map sensor. Worse than before. YIKES! Couldn't even get the car started. So I went back to wiring the 3 bar back together and guess what? BOOM, even worse than before. Can't even start up the car. Might have to buy a new 3 bar and install it. See if that works. Then try to troubleshoot the 02 Sensor and hopefully get a new chip installed. So far no good.
