I have a 96 Ek hatch with a GSR. well ill start out how it happened. It ran fine one day the next day i strarted it up, started fine went down the road, went to rip on it and bounced at 3.3k. No idea i checked for the CEL i was getting 15 and 41, So for one i needed a new harness cause it was chopped so i got a new y7 put that on and got a new chipped ECU. i put it in ran fine. But the chipped had higher redline and two step so i went to use them. redlined at 7k and non of my tunes were in it. So i looked into the ECU there was a On/off switched turned it on and now its back to the 3.3k Redline? I need some help im getting fed up trying to figure out what it could be.

 

What are you bumping for? You just posted this?

 

Im just trying to get someone to look i need this figured out ASAP. i have no idea what it could be. im trying to get it ready so i can go to Maryland tomorrow and its not being friendly

 

If it's that big of an emergency then take it to a shop. You are aware it is the weekend and not everyone that is even on the forum is capable of answering your question?

 

that's fine just getting a second opinion before taking it anywhere? calm down. Do you know what it is, if not then why do you care?

 

Address the CEL codes that you forced when you "ripped on it". Since it is not a stock ECU, it could be anything.
15 Ignition output signal
41 Primary oxygen sensor heater

 

no cause on my ecu i can turn it On or off and when i turn the ecu switch on it does it and when i turn it off its fine. I have no idea i still can't figure it out i got a new ecu to and it still does it. and for CEL 15 could my distributor cap and rotor being bad cause it?

 

WTF is the switch for? First time I've heard of a switched ECU. Somebody school me.

 

I have no idea I bought it off someone I I'll take a picture and post I
It

 

Are you sure you're talking about an ECU?

 

a switch on an ECU? post some pictures.
but if it was fine when the 'switch' was off just keep it off?

 

 

I know it sounds Wierd but I swear. And if I leave it off it doesn't run with my chip

...I've never heard of this either

 

Whaaaaat? The ECU usually chipped. You HAVE to be talking about some piggyback unit or something. Where are the pics?

 

is it just a little metal round toggle switch on the cover of the ecu?????? You wouldn't by chance live in Oregon would you? Or maybe got that car or ecu from someone in Oregon?

 

Ur ecu is prolly on limp mode.. Its happen to me b4... Either u get ur cel fix or try swapping a differe.t ecu.. From a friend or some1

 

I got it to work. It was throwing cel 15. I'll still post these pictures and no it's a lil switch by the chip the size of a pen tip. Had to check the distributor. Thanks for your input I'll post those when I get a chance. It was running in limp. Wierd but if anyone has this problem the way I fixed it was I put my chip in another p28 it rebase map te chip to work. Wierd but worked.

 

Pardon me for saying, but this sounds like gibberish.

 

English is not our citizens strong suit anymore, Ebonics is the wave of the future!

 

The switch that he is talking about is common. When you chip an ecu there is a jumper that you have to use, if you switch the jumper you can actually run the ECU as stock, otherwise you run the map that has been loaded to the chip.

This might be an old thread but I had to say this, came across it while having a different problem on a GSR swap.

 

Funny, I'm looking at the guts of a chipped ECU right now. What jumper are you referring to?

 

I believe it's labeled RP18, grumble. Cut the wire to run the stock tune, solder a wire in to run the chip. It's also possible to run two different tunes this way, if you can replace the "factory" tune with something else.

 

I'm not talking about cutting wires. They keep talking about jumpers/switches. I haven't seen one yet.

 

yeah I have seen this before.. My friend had one in his boost hatch so he can switch between his rac gas and pump gas tune it was pretty sick. I believe he was running neptune? Im not sure how it works tho lol
