ok so the best bet is to replace ecu with a non immob ecu? Gaz said he has had problems doing so. All I can tell you is that I have seen a '95 c18nz running on a pre transponder ecu with a key missing it's chip, it is therefore the path I would look to take.. Update on this issue.. i went for the c...

Hi, im looking to replace my ECU on my Cav C18NZ 1995, are the plugs on the ecu all the same? or is their any differences with age/engine type/immobilised etc?

thanks

Other issue i have with the remote central locking is, when i go to lock the doors by the remote key, the drivers door does not lock? but all the rest do :scratch i then unlock with key, open the door and it sets the alarm system off and the only way i can turn the alarm off is to unplug the central...

Depends if you known someone that has the kit to program it without going to the dealer, and if you have the security code I guess. Dealer will probably not be comparable to recycled units. Just make sure they come from the same car if you go this route. ok, and what about if i got another immob ec...

ok is that a costly job to have it reprogrammed or would it be cheaper for me to go to a local scrappy and get another set? also would a vectra ecu work on the cav? thanks

Do us a favour and split the key in half and take a pic of whats inside and post it up. The key might look like it doesnt come apart but it should do. heres a pic of the keys i have with it, the open one is for the doors, the one un-opened one is for ignition, sooo the chip must of been taped or st...

The barrel slipping out moves the key away from the receiver ring, which will affect it, been only if there is a chip in the key to read. When the immobiliser has an issue the engine management light will flash at a rate of once per second. Yes the engine management light is flashing rapidly when i...

ok, i have now changed it all back to how it was before i attempted it, i.e using the original key barrel, cav transponder and cav central locking module and again.. no change? Also my ignition barrel is broken by as soon as you turn the key the barrel comes back out again.. would that cause an issu...

ok so the best bet is to replace ecu with a non immob ecu?

sorry i ment, with the ignition switched on?

I tried it but still no different?

Was thinking of sending an live ignition feed directly to the fuel pump to see if that would fire it up? any thoughts?

its one of the old round-ish keys that you cant open up?

So you have a cav that has the transponder around the ignition barrel but you haven't got a chip inside your key? Have you lost the chip? Have you dropped your key recently? If you never had a chip in your key maybe it was strapped to the other transponder that you took off? Yes no chip inside the ...

Hi guys, ive got a problem with my cav Immobiliser, its a 95 1.8 GLS, its got the transponder around the ignition barrel and the key does not have the chip inside? But was starting up fine with it. So i recently had a go at doing the vectra b remote locking with the megamos box and remote key, but w...

Thanks, yea i prefer this colour too, i had a 92 cav sri 8v in the same colour and had a few subtle mods on that and i loved it! So hoping to do the same with this one!? :D Yea ive only had one other 'ecotec' and ive never had any problems with it so im a kinda newbie with these engines, but i would...

Thanks! Lol yea i know what you mean, so will probably run the 'Ecotec' into the ground and then eventually replace it with a REDTOP!

Just bought this cav in part exchange... DSC01072.JPG DSC01074.JPG It the 'Ecotec' GLS model which i paid £50 and px'd with my old cav 2.0 8v for. Its abit tatty here and there but nothing major that the old 'elbow grease' couldnt cure! The only things it needs is another cambelt tensioner pulley, t...

Ok thanks for all the info, so has anyone got any springs for sale???

Ive got 17'' alloys with 205/40 tyres on my cav, i want to lower it but not sure how much i can get away with? I know that the rear is higher so would obviously be different then the front. Anyone got any ideas?? And ive heard that some people cut the springs instead of buying proper lowering ones, ...

Hey guys, thanks for the info... It turned out to be the control unit So i changed it over with the one out of my other cavvy for spares and it works!
cheers

The idea i got now is to do what you guys suggest for a 1.8l head on a 2.0l block etc so ive got 'PROJECT LS' back! And now going to swap bits over from my new 2.0l GLS saloon to the LSI!
Do i keep the 2.0l gearbox with the 1.8 head on the 2.0l block??

SOLD this cav now, i got a new one..... 94 L REG CAV GLS 2.0L 8V Saloon!

See New Post!

Recently my central locking has decided to give up working... when i turn the key to lock or unlock it makes the locking sound that comes from the boot like it wants to work but dosent. Its not the fuse, could it be the relay? and if so.. does anyone know which relay is for the central locking?? Che...

Hey guys, ive just put a set of FondMetal 16'' 5 Spoke Alloys on my 94 Cav 2.0l 8v Saloon, ive had them all balanced but im still getting alot of vibration mainly from the front end, ive been told that they may require spigot rings as there is a gap around each wheel on the hubs but if not could it ...

Ok thanks, sounds great! Think il get that done then! Anyone selling any of those parts??
