|  ECU remap for the new Corsa 1.7 CDTi?
Anybody ever heard of one of these being done, 'cause I'm having terrible trouble finding a company that'll do it. I've tried all the obvious ones and they don't do it. It seems the new Astra 1.7 is supported, so why not the Corsa!?
Thanks

try celtic tuning, they often want new cars to test and create the software for by dyno'ing it and tweeking, and for you lending them your car they give you a free remapp

Have you tried angel tuning? glctuning and vtune? You really need CUSTOM remappers rather than the one map fits all suppliers that download generic maps from their main franchisee.

gcltuning look like they can do it and at only £310 for their mobile service. I'm waiting on the others. Just need to figure out how much more it's going to cost me in insurance - hopefully not too much more, as that's part of the reason why I got a diesel - low insurance premiums!

You should get a quote first - insurers know damn well that modern diesels with a performance remap easily outrun cars with similar sized petrol engines. If they suspect foul play they will inspect your car in the hope they can refuse to meet a claim. Driving without valid insurance is a serious offence and costs ten points.
Vauxhall has done well to get 130bhp out of this in factory tune. I have to say I'm impressed. |

It appears not. Or, not yet anyway. | |

Most of these sites will quote for the old Corsa - the new Corsa (D), 1.7 comes with a basic 123bhp - so I'm expecting to get around 150bhp after a remap. As far as insurance goes, I'm definitely not doing anything until I get a quote and see what the difference is - one of the main reasons for me getting a diesel was the low insurance premiums, so don't really want to end up spending the same as I would for a petrol engined car.

Modern diesels go very well indeed. The insurers know this, too. You won't get away with an old fashoined diesel insurance premium with a car the delivers 160bhp in performance map guise. | |

| Re: ECU remap for the new Corsa 1.7 CDTi?
yeah the ecu is new enough to learn small changes that would be made by induction kits and exhausts if you do these after.
although you will get better results if you do them 1st and then get a full custom map done for the car.

One option which is possible is to dump in the 1.9CDTI engine out of an Astra. Thurlby Motorsport have the Astra 888 which is tuned to 200bhp.

That would work but it's a bloody costly way to go. You'd have to start with a CDTi 150 unit if you want to go all the way to 200bhp.

| Re: ECU remap for the new Corsa 1.7 CDTi?
hey there pgarner.. I've already done a sports exhaust and replaced the stock filter with a K&N flat pan filter. guess the next thing to do is to re-map then alter it when i do more. is it possible to run two different maps like others have said? one for economy and then one for proformance? | |
