A couple of weeks ago I had a Haltech installed. Because we were rushed it only got rough tuned. It runs extremely rich and I was warned not to boost it at all. The car made it home fine. It drove ok for about 2 weeks and now it is acting like it is running on one rotor. Could this be caused by fouled plugs or carbon build up from running extremely rich. Please help me because the car ran fine before this mod and there shouldn't be any reason why my motor would be dead. BTW I never boosted the car during this time. I have done somewhat of a compression check. I took out a plug and listened for the three loud swooshes of air from each rotor. Both rotors sounded the same. They both sounded like they had good compression. I'm going to change the plugs tonight and see what happens. Any other advice would be greatly appreciated. Thanks.

yeah it could be fouled plugs. ive managed to foul a couple



mike

did you look at the plugs while you were doing the compression check?

Could be fouled plugs, trailing and leading plugs mixed up, or really really bad timing.

i'm leaning toward fouled plugs

post your map up, and we can critique it https://www.nopistons.com/forums/pub...#>/biggrin.png



mike

haha, yea thats a good idea

I don't think you want to see my map right now. You guys would probably laugh at it because it's running so rich. I changed my plugs tonight and it helped some but I think the timing needs more adjustment and the fuel map needs to be leaned out some more. Thanks for the help guys. One more question. Does anybody here know of someone in my area that could possibly show up at my place with a flatbed trailer and tow my car to Fort Worth so that the tuning can be finished? I know this is a big request, but I'd be willing to pay for food and gas and some extra for the persons time. If so please reply to this post with there name and number and let them know(if you're not this person) that I'll be calling them.

put in new plugs and get some dyno time and redo the map. haltechs are big pains. AEM ECU or the Greddy e-mangment system are a better deal. haltech are a big pain https://www.nopistons.com/forums/pub...1047683358.gif

Well people have told you about the fouled plugs and timing but what about your o2 sensor. Just trying to help but I think I have been gone for to long now to even try and help.

Get your Haltec tuned, get your self some new plugs. and you should be fine.

Eddy we don't even have the o2 sensor hooked up. I'm getting like 120 miles to the tank of gas. This thing is really confusing me. I almost wish I hadn't installed the damn thing. I'm going to trailer it up to be tuned. I don't even want to drive it right now. ****, I tried starting her today and she wouldn't even start. I'm really confused right now. I just want my car to run right.

it should be great once it's tuned, you should be able to street tune it well enough to make it liveable, it sounds like the maps are really bad currently.



can you post them?

Unfortunately I can't because I don't have a laptop to down load them to and the upload them here. Do you really think this thing will still run, even after everything I said it is doing? You don't think its blown? Would you know of any reason why it could be blown(using the info I've given)?

nah it shouldnt be blown. a fouled plug and a blown motor sound the same, ive fouled the front rotor on the 20b tuning it several times



mike

it had good consistent swooshes so it's probably fine, i think it's all in the tuning now. just be careful.



the haltech should be great, it just gives you alot of control, not much is done for you to make it very easy.... but you can use that control to get your engine performing better than it ever was on the stock ecu.

Thanks guys, this makes me feel more comfortable. I hope when I get it up there next week that it will run correctly. Then things should be better in my household. No more pissed off wife because I'm spending to much on an old car. She understands why I'm spending so much, but she doesn't like it.

For right now just concentrate on getting the car tuned and work from there. Take it one day at a time, it's worked for me. Good Luck.

yeah, dont worry the haltech takes a while to get right, especially if you've never done it before.



mike

I've never done it before, but I'm not the one who is tunning it. The guy who did most of the initial tuning was Brian Cane. He knows his second gens, but we just didn't have enough time for him to get it all done correctly. Hopefully he can help Steve Kan finish it, if Steve needs help.

Well I did some work on it yesterday and got her to run semi correctly for a while. She was extremely flooded, so I used the unflooding/ATF trick that Rotary Performance has posted on thier website. After I did that and put my old plugs(cleaned of course) and old O2 sensor(just to plug the hole in my downpipe) back in I fired her up. She ran fine. Of course she smoked from the ATF, but that cleared up real quick. Now all I need to do is change the oil and put my new plugs and O2 sensor back in before I take to Steve to be tuned. Guys thanks for the words of comfort. I can't wait to drive and boost her when she is tuned correctly. I think it will be so nice.
