What's available for tuning for this model, I know it makes around 200hp.

I cant remember off hand what injection system I have eg Jet/tri ect.

Now I know most tuning is really just a question of big your wallet is. Is it the same for this?.

I was reading certain articles from various site ect, saying that most tuning thing's are geared for later models from say 93/4 onwards, thanks for any help on this.


BTW, it's an auto!

You have LH Jetronic fuelling and a separate APC box with direct ignition. Like me (1992 2.3T) you will find that there are scant tuning options for this model. If you car doesn't have TCS, Speedparts will supply an APC + Jetronic upgrade which takes it to around 254bhp if my understanding is correct. Abbott do APC boxes only for 1990-1993 APC's and this takes power to around 240bhp.

HTH

P.S. Regarding the autobox, some people have had problems tuning auto's others have been OK. Just bear in mind that it is an acknowledged weakspot in 9000s!

Thanks Jason..........Not been using it for while (been using the other and the bike), so cant remember off hand if it's got TC or not will look tomorrow.

Yea Iv'e heard a few horror stories about auto box's, I'll have to be very carefull!.

I do have a fsh with it right enough, but I do get a kinda "sqeak" kinda noise when changing from 2-3, mostly when it's warm.

I'll check these site you sent, I'll send Speedparts an email. Providing I dont have TC, again thanks for that

There are two theories about this (I think which one applies depends on exactly what kind of squeak it is, since a lot of things can be described as a squeak).

One is that this can be cured by an additive to the auto fluid (search the forums for more details)

The other (from the auto rebuild specialists that DCA use) is that this is the beginning of the clutches slipping, and a rebuild is in the box's future (and that the additive certainly won't make any difference to that). They said that it might not get to the point of requiring a rebuild for as much as 30K miles - my box (which has that squeak)has done 10K after that diagnosis without it getting noticeably worse

Iv'e also heard that most times they dont work!.

The only place near me who rebuilds auto box's (and are seemingly very good, but very expensive) are Mackie in Glasgow.

But when I had my BM I took it there and was told it be £1700 inc vat to overhaul it
. So as you can immagine I dont want to put it in there, because it quite simply isn't worth!!, I can buy another car for that!

I think you can upgrade to a Carlsson APC which will give you 220hp, coupled with a manual boost control valve will up it safely to around 240....a lot cheaper option IMO.

The problem with an MBC is that it will tend to boost the torque lower down the rev range, and risk damaging the box. The safest option IMO is to get the right software.

The other problem with an MBC on an APC system is that you run a MUCH higher risk of running lean. With LH systems the fuelling will not be able to adapt to the higher boost as the APC is not "telling" the Bosch ECU to up the fuelling. Personally I won't touch MBC's as several people who post here have had engines killed by MBC's, I'd rather save up for a remapped or tweaked APC.

Yea your both right. it sounds as if going for the proper upgrade is the thing to do.

I got an email from Elkparts and they said if the car does have a cat and doesn't have TCS, they come do "thing's" with it.

But you said that anyway, no I wouldn't trust myself with the MBC no way!
