superchip/dastec, next week, advice please.

[Ashley h]

hi all,
Apologies for posting yet another superchip question, i know there are always loads but i couldnt find exactly what i wanted using the search function.
Anyway, i have £450 spare as i was going to buy a computer, but im now not going to,
i have a 99V 155Hgt , i thought i'd spend this money on the car so have decided to get a chip of some kind in the next week or two.
All i have is a bmc cda.
I have heard of the hgt's having superchips but could someone please advise me on what chip to get to give me the best gains. I know im only looking at a few horses but it's just lost its edge since the 17's went on.
Also do these chip places give you a readout of before and after figures?

Any help is greatly appreciated.

A 'chip' and a dastek are somewhat different.

A chip just replaces the map in the ECU with one based on a remap they did a.n.other car. The issues are things like did the other car have a different air filter, what exhaust, how old was it etc..

The chip may have been mapped for a stock HGT with half the milage of yours.

BUT its a fit and go job.

A dastek is a piggyback ECU. They come blank. They have to be tuned on a rolling road to specifically work with YOUR car. ie the map will be tailored to the exact state of your engine, not someone elses. This is why they cost more.

What you can also do is then take the piggyback and fit it to your next car and have it tuned for that car.

cheers for that tom, i guess its the dastec then, £375+vat ive been quoted, does anyone know if thats the going rate? also has any other hgt had one of these?-if so what were the gains.
cheers

375 sounds pretty good to me if that includes fitting and setup

Look to the second / last bit of this post for advice on the Dastek

cheers for that nico, i gave it a god read and im now beginning to wonder whether its worth it. My bravo has done 50k and runs fine all the time as i look after it, it just seems that there is nothing there below 4k revs which is really frustrating, if i knew that getting the unichip would give me a bit more low end power and even 5+ bhp then i would definatly get it. i get the feeling that i could spend money getting it and not really notice much of a difference. The dastec guy said 8-10 bhp but i know thats probably bull. Realisticly what bhp/torque increase would i get? if any, and would i notice it?- in your opinions.

Thanks again

Those losses lower down the revs are entirely attributable to my cams. I was disappointed with the loss low down, but actually it only makes me drive more the way a hgt REALLY should be driven. 10bhp gain without em is not unreasonable from the Dastek. We would see much more torque than top end bhp if only our ECUs were not so restrictive staying closed loop (a Dastek can only achieve so much).

If you've got 450 to spend, the best possible thing you could spend it on(rather than your engine) is some adjustable FKs (I'll get jumped on for mentioning em cos I still havn't dug out the details for the supplier I'd arranged the discounts with). You might have your car lowered already, or you might be plagued with speed humps where you live, but if not, they are without doubt the best value mod you can buy to improve your driving enjoyment, imo at any rate.
