Fish and Chips, Chips, Chips

OK Guys,

I wanna know who has had their ECU Chipped or remapped and who did it, how much did it cost and was it worth it?

How much better is the performance now ?

What car ?

If it's an NA engine, then don't bother.

If it's a Turbo, then stick to your specialist tuner.

If it's a Diesel, then stick to

or

agreed

or if it's got specialist mapping via some jiggery and, or, indead, pokery with aftermarket ignition and wild cams and that sort of gubbins

van aaken are supposed to be the dons at diesel tuning, but their other work doesn't have much of a rep according to people who slag them off all the time about certain turbo conversions

Right, I have an off the shelf superchips chip from errr superchips on my

1.8 focus for 2yrs now. This was for drivability reasons rather than seeking massive performace gains.

I havent timed it to see if it is any faster, but pick-up throughout the rev range is now alot better- felt like accelorator was attached to engine via long elastic band before and you can stay in one gear higher most of the time. There was a flat spot at around 3000rpm that is now much less pronounced and whereas the power tended to tail off after about 5000rpm it now pulls alot harder to past 6000 if you wish. I have kept up with a 2litre Focus with ease.

mpg averages 36mpg in mixed brisk driving; it will do 430miles on a tank. The superchips modem dealer chassis dyno showed 116 (corrected engine bhp) before and 124bhp after the chip. They didnt have the capability to measure torque.

cost was £299 for the chip, and the dealer charged £60 for 2 dyno runs plus vat.

I would say it was definately worth it, especially if the standard ecu software makes for a less than optimal drive.

Hey, as far as i was aware, chassis dynos measured torque and converted that to power! Given that power=torque*rotational speed in rad/s, shouldn't be too difficult to work it out! i would take corected engine bhp with a bucketload of salt as well. chassis dynos are really only for comparing setups, not measuring absolute figures.

I had a superchip for the 1.6 16v astra. I had to take it back for adjustment as the ignition timing was way over-advanced at low revs which caused momentary pinking every time the throttle was applied.

To be fair they did "adjust" the mapping for free, and that resolved the problem. However, it had flat spots on normal unleaded thereafter and worked best on Optimax or SUL.

For diesels I'd avoid superchips and go with Van Aaken. They seemed very knowledgeable and helpful when I spoke to them. The only reason I haven't bought the VanAaken box yet because the money has gone elsewhere now!

Bah, what the hell are you doing man !

You're quite correct, i could work out the torque...

I know chassis dyno's are notorisously in accurate, but as ford suggest

113PS as standard for the 1.8 Focus, I thought it close enough. That there was some increase in 'power' and more importantlly drivabiluty was much imporved was my aim.
