Ok, fellas.... I need some help!

I just swaped in a 2.0L JDM GSR into my '99 LS this weekend. Here is the setup:

Import Builders Re-build GSR w/
- Golden Eagle 'Godzilla' Sleeves bored and honed to 84mm
- Eagle Rods
- Wiseco 11.8:1 Pistons
- Skunk2 Stage 2 Cams
- Skunk2 Cam Gears
- Portflow Valve train
- R/C Engineering 440cc injectors
- Hondata Stage 2
- Balanced Crank
- All new pumps, bearings, seal, gaskets, etc.

The problem is that since I'm using the Hondata, I need to run an OBD1 ECU. However, I.B. sent me the wrong OBD2 to OBD1 Jumper. And I need to get to work.

Several people advised me that I could run the Engine off of my LS ECU and it wouldn't hurt anything since I would be babying it anyway while I was breaking it in. That way I could at least get to work.

So, I tried starting it up with my LS ECU, and it turned over when it was cool and idled ok at around 1500 RPMs. But after it warmed up for 10-15 minutes, and the idle stepper drops the idle RPMs down and then engine just wants to die. It won't run anything under 1500 RPMs. And then since it is warmed up, and it wants to start up at the normal idle speed (around 700 RPMs or so) and the thing just doesn't want turn over. It it sputters and spits for a few seconds then dies.

It was suggested to me that the MAP and TPS sensors could be mixed up? So, I tried again the next day while switching the MAP and TPS sensor. This time it wouldn't turn over at all. The started cranked away, and... nothing. Even when it was cold. So I switched the MAP and TPS sensors back... and still nothing.

Do you think it is just because the LS ECU is running my engine way to rich on the 440s?

Do you think it will run fine once I get the GSR ECU and Hondata hooked up with the JUMPER?

Or do you think there may be something less that isn't right?
Because there are three things that are not hooked up.
- One is what I think is the Crank Position sensor. It pluged in right under the crank pully on my LS, but I can not find any place for it to plug in on my GSR engine.
- Another is a plug that is wired in with the MAP and TPS sensor. I can not fine any place that it is suppose to go.
- The third is what I think is an EVAP line that run from the canister to the I.M. on my LS Engine. But I can find no such place for it on my GSR.

Do you think that from the first time I ran it, and it warmed up and stalled, and from me tring to get it started, the rich a/f ratio soaked the spark plugs. And that is why it wouldn't do anything the next day (although, I wouldn't think they would still be wet the next day)?? And as I kept trying to start it the next day, the plug just keept getting soaked??

I'm opened to suggestions!!!!!

I should be getting the correct Jumper today. And I want to get it running ASAP!!!!

Thanks for your help!!!

 

Is the IACV hooked up?

 

I believe so.....

The car is at my friends house (who helped me do the swap) right now. So I can't double check and verify it for sure.

But.... I believe so.

 

The IACV, TPS, and MAP sensor plugs all look the same, and will interchange. Make sure you have the right plug plugged into each sensor.

 

Good call inspyral... also, what in the hell Codes are you throwing???? You need to check that...

 

Finally!!!!!

I got the Jumper last night. And got it running!

But when I pluged in the GSR ECU and Hondata... the thing wouldn't turn over at all. Needless to say.. I WAS PISSED! So I pulled the spark plugs.... they were charcole black!! (Man, that LS ECU must have been running RICH AS HELL, because they got that way from a total of idling time of about 25-30 minutes. So I went to the store bought a cheep set of BOSCH to give it a try, replaced them. And it fired up like a champ. Now all I have to do is finish up the Vtec wiring to the ECU. And work out a few minor glitches:

1. It idles kind of rough at around 600RPMs. It should be at more like 800RMPs (says Jeff@I.B.). But its a real bad idle... when I let off the gas, it drops downt to 500 or below sometimes.. almost like it is going to stall, then it rebounds and holds fairly steady around 600 or so. But I'm going to have to try to take care of that.

2. I need to adjust my ignition timing to 13 degrees after Top Dead Center for now until I get it tuned (says Jeff@I.B.) I know how to do it. But with my car, I'm not 100% sure how to know what the timing is set at. The only mark I can see on my crank pully lip is one white mark (which I believe to be the TDC mark). I can't see any others. So I'm not sure how far way from the TCD mark the little indicator on the plastic guard should be. Any advice, suggestions, ideas?

3. My power steering.... FIXED [edit]

4. Also, there is a slight 'whine' or 'whistle' when the car is in 5th gear. But only when the clutch is ingaged. Advice, suggestions, ideas?


Oh, and one other thing.... are those spark plugs ruined? Or can they be cleaned up? If they can, how/what do you use to clean them up? And is there anything else I should worry about since the plugs where so bad from the engine running so rich? Again... I didn't actaully drive it... it just idled for about 25-30 minutes.

(PS civicon19s, I wasn't throughing any codes on the LS ECU... and I'm now on the GSR, but I having wired up the Vtec wires yet... I'll see if they go way after I do)

Thanks!

And thanks to everyone who has helped me out so far!!

 

1) try adjusting your idle adjuster screw once the engine is warmed up

2) http://www.c-speedracing.com/howto/timing/timing.php


3) Is the pump working? Is the belt on? Are the lines connected? Is the belt tensioned?

4) :dunno:

I would not reuse those plugs. Just spring another $2/ea and get some new NGK coppers.

 

Yeah, I know... but I don't see the Three marks that are close together.... I only se one mark... that I think is the 0BTC mark.

 

Look at your crank pulley with the engine off. Find the white TDC mark, and then look toward the front of the car. You should see a red mard surrounded by a brown mark on either side. If your crank pulley is stock, they should be there.
