Dunno. Install works automatically on my XP and my Vista laptops. Just throws a wobbly on both of the Windows 7 (32-bit and 64-bit) machines. Until Joe says what interface he's got, we're kind of stabbing in the dark.

Somebody with an Opcom should help the poor kid/car out of it's misery...

[techieboy]

Would happily go over to Joe's but can't do it before tomorrow night. By which time he might have torched the car.

To be honest I'm falling into the fcuk the car fcuk time attack and restore back to stage 2 and sell it. Had enough of this crap.. I know it's alot to ask for but all I want is a working car!!! and breath...

First on the Harrop

[techieboy]

Want me to come over tomorrow evening Joe?

[alanoo]

Tried recalibrating the wideband ? Maybe an injector stuck on ? A FPR issue might be possible too... I'm sure the lack of error code is again something deactivated in the map by courtenay... makes finding the cause much more difficult...

I once remember watching a bloke balancing some carbs on an eType holding a screwdriver to his ear whilst holding the other end somewhere on the carbs Times change.

keep your head up bud. You will be laughing about this in a couple of weeks. Nothing is easy when it comes to VX's but your sooooo close!

Presides wouldn't this just give an air leak and erratic idle?

Probably.
But with jakbvx problems with that bracket and it's sensitivity, it could be worth to put removing the spacer on the test list as plan Z, if all other stuff/tests fails.

Do you have a list of differences between your and Nicks car?

[alanoo]

As I, again, forgot you had the ECU conversion, I'm sure it is something that a normal ECU would have detected but has been deactivated on the ECU conversion.... truth is I doubt it is fixable at all without the mapping tools.

[Exmantaa]

His ecu picked up the p0170 code when the O2 was disconnected, so those ecu systems seems to function properly. But for sure a bunch off codes is turned off and most likely also the complete 2nd post cat O2 sensor system. Just googled that p0170 codes on a Z20LET were also thrown due to a dodgy/oily MAF sensor, so check that after you confirmed the correct O2 workings. (Do you have an oiled open airfilter before the MAF????) But am I correctly reading now that you throw the towel in the ring and bring it to Courtenays to sort it out?? No offense, but how do you expect to handle such basic engine problems then during the heat of Time Attack session if a sensor gets dodgy? The engine ran pretty OK with this base mapping. That mapping is not changed, the engine is mechanically OK. We assume his injectors are not suddenly flooding the engine, so first check is if one of the sensors is going bad on you. And sensors that influence fuelling are O2, MAF & MAP and all can be simply checked... (multimeter / laptop + Opcom or other.)

[The Batman]

Yeah I also googled it and saw that hence why I have another maf on its way to me aswell as another brand new O2 sensor. Thats a little unfair towards time attack..... I'm a pretty good fault finder usually, but I have seriously fallen out of love with the car at the moment. Also I have ordered op com

You and the car have to re-connect again, so get your Opcom link working. (You dremel must burn-out soon anyway, so then you cannot flee anymore from this... )

[The Batman]

Dremel is definitely starting to smell funny! I will get it sorted, the bodywork mods are making me fall back in love with it

[The Batman]

Oh and I think I had a standard cable not an opcon cable so would explain why it wouldn't work

[Exmantaa]

Can send you my spare Opcom if ordering (from China) is taking too long.

[The Batman]

I ordered one from the uk, well atleast the advert said they where based in the uk... Thanks for the offer though I will change: Maf 02 sensor Map sensor In that order

There's two kinds, one is an OP-COM interface which is specifically for GM cars and has a different pin connected in the plug, so it talks to ABS and airbag etc.

Then there's a generic ELM-327 interface, which will talk to pretty much all cars but in some cases doesn't talk to everything (like on our cars).

If you have an OP-COM then you want the OP-COM software to use it. If you have an ELM-327 interface, you can just use a generic OBD application like ScanTool or Engine Check.

If you're using OP-COM, it barfs on the configuration of the drivers but does install everything you need. When you plug the cable in, WIndows will tell you it's trying to install the drivers then fail after a while. You then need to go to your Start button and click on it then you need to right-click on My Computer. It'll bring up a new window with a link on the left hand side for Device Manager. Click on that link. Now if you scroll down the list in this window, there should be a device with an exclamation mark at the side of it called OP-COM USB v2 interface. Right click on that and click on update driver software. In the next window, click on Browse My Computer for Driver Software and point it at the C:OP-COMdrivers directory and it should find the driver okay.

Obviously, all of the above is bollocks if you haven't got the OP-COM interface (although some of the manual driver install might apply).

My OP-COM interface looks like this:



My so called TECH-2 interface which I've never been able to reliably get working


And a crumby universal generic ELM-327 OBD interface

this one come in the post today and had to install it and your instructions where perfect

will give it a go now
