Congrats on the new baby wink

Are you buying the old car back off the insurers?

nono Doesn't seem much point really.... weeping Not even bothering with the wheels & tyres, they weren't that good, just new tyres, and it is too much hassle with no car to get them, plus would be a day off work - for which I won't get paid (and could buy new tyres with hehe) and don't have the time (as busy at work for once hehe) frown

What would you reckon you could have it back for? It looked a minter and surely there must be someone on here to put TBs and aftermarket management on it (which would make for an effing awesome little car IMO).

Not a clue, but someone could buy it and get stuck with it, as there is no way it will run again short of a new engine, imobiliser, keys & key barrels..... And they will still be stuck with a Cat D car......

That doesn't make any sense to me - there's nothing wrong with the actual engine, is there? Of course it will run if you strip it from its current engine management and put an integrated aftermarket system in.

It'll probably work fine if you put an ecu from a different year 1.8 in it. It's only a problem on that one because on later cars they built the immobiliser into the ecu and it's getting that working that's the problem (I think). The car itself is fine so either replacing the ecu with an alternative Mazda item or an aftermarket ecu will get it working. Seems a shame for it to end up at a breakers where they will sell all the parts (including the current ecu) for a profit which you could be making yourself.

In fact, find out how much they will want for it and I might buy it off you myself!

I rang, but its gone.....

But bear in mind that they tried another ECU of the same age in it, and that is is Mazda that have told them that from the records of when they were built the ECUs for this car are not interchangable, it is a new one that can be programmed or the scrap yard for another '98 1.8i Classic.

Doesn't bear any consequences if you scrap the whole lot and put aftermarket manangement in it (which would get rid of the immobilizer, obviously).

Both Mazda and the Insurance Agent have been trying to fix her for a month, I would have thought they would have tried this, seeing as they tried just about everything they could - scrapping her really was not something they wanted to do frown

Lets face it, the Insurance Agent wanted her fixed. He should not, in all honesty have been involved, it was not an Insurance job after all - they don't cover mechanical faults.

She's gone to the scrap yard, it is all null and void now anyway frown

Mazda & Insurance would have their hands tied on a repair like this. They have to use Mazda parts and only those that are listed for the car. It would have been fairly simple to get an earlier ecu into the car, even if it meant taking a wiring loom from the earlier car too. Plenty of people change the engines, ecus etc in there cars - the only complication in this case is the immobiliser built into the ecu but that can be easily worked around.
The thing is, Mazda and any insurance approved garage wouldn't be allowed to try work arounds (more commonly known as bodges wink).

But as the car has now floated off to the great scrap-heap in the sky this discussion is redundant frown

Believe me, neither would mandate a 'modification' as (perceived) hardcore as putting in aftermarket management (they'd, indeed, rather scrap a perfectly good car) - but OTOH it's exactly what you would do as a PH--type punter confronted with a car like that that could be bought cheap from insurance, p'haps as a track car at the least.

But that is just it, they somehow had managed to get permission so that they didn't just have to use Mazda parts and were allowed to try the 'bodge' jobs. Otherwise she would have been written off a month ago, I'd have bought her back and got someone to try to fix her for me.

I asked, but he doesn't even know where she has gone - they just get collected & taken by a firm of contractors.

It'll probably be in the back yard of somewhere like Autolink or MX-5 Heaven by now then to be stripped down for spares.
