SuperChip problem

henleyryan · 12 Jul 2011 at 18:17

Hello,

I've had a superchip map programmed into the car last week (from a reputable garage) which is meant to change the BHP from 139 to 172 and the Torque from 353NM to 432NM. I'm of the opinion that that is fair old change and should be definitely noticeable but I can't tell the difference. I had been driving the car for about 6 months prior to the chip yet as soon as I drove out the garage and now for a week on the road, I still can't see/feel any difference at all.

First thing, does everyone else agree that an increase of 80NM would be noticeable.

Second, is there a way of checking that they have actually done something? I was thinking a g-meter?

Cheers
Ryan

What car gives such low BHP figures, but massive torque?

a diesel?

he is also quoting torque in NM rather than lb/ft

Fair point, missed the NM bit.

I re-mapped my vectra from 150 to around 195 bhp and noticed a considerable difference. I would go back to the garage and get it checked out...

What car is it..?

henleyryan · 12 Jul 2011 at 18:32

Yes a turbo diesel, Citroen C5 2.2D. Don't all turbo diesels mave that much variance between Tq and Bhp??
Citroen also do a 2.7l V6 diesel now that has (after superchip) 239BHP and 528NM of torque, that'd be a fun drive.

NM was the first torque figre I heard about and it's stuck with me. Similar to measuring your economy in MPG but filling up your car with litres, the typically british metric/imperial combo.

did u get it done properly on a RR or just some one pratting about on a laptop ?

henleyryan · 12 Jul 2011 at 18:37

The process involved the garage reading my map off the car, e-mailing it to SuperChips, them checking my map for anomolies, e-mailing the garage a new map, the garage flashes the new map. Voila, an apparently faster car.

The garage said they don't do the RR for stuff from superchips because there is usually no point, if superchips quote those figures then they are usually right.

Sounds like they have messed up the flash somewhere along the line. I did mine myself using a custom astra 888 map and it is a very noticeable difference and I have not RR mine.

I had my previous car remapped from 150bhp to 180bhp and noticed it instantly - a massive difference.

*Moangroan* · 12 Jul 2011 at 18:42

Well on a diesel I would think 30bhp would be noticble...maybe not round town but overtaking someone when you are already doing 70 should see a difference and a cloud of black smoke to boot.

crinkleshoes · 12 Jul 2011 at 18:42

That kind of increase should be instantly noticeable!

With those figures... sounds like a 2.2->2.5L turbo diesel to me

EDIT: Slow posting... at least I was right about the 2.2L bit lol

Fr0dders · 12 Jul 2011 at 18:48

only way to tell is is do a before and after dyno on the same day

no_1_dave · 12 Jul 2011 at 20:51

It would be very noticeable!

Haze · 12 Jul 2011 at 20:55

i had mine done like u had yours done,, i would not rate superchips very highly at all

had it done again by chippeduk, was much better after that

Peerzy · 12 Jul 2011 at 21:28

Seriously, do it properly.

Live map by someone who knows what they are doing, with before, during and after runs on a rolling road.

Let them tweak it till you are both happy.

Absolutely.

I'd advise you get it re-flashed asap. I would personally be vary wary of running with a possibly dodgy map (not sure if its such a big thing with a diesel or not but know of a few RS Sierra & Escort owners who've lunched their engines after a crap re-map)

I don't understand why people risk completely wrecking their engine to save a couple of hundred quid on the difference between a generic chip and a proper live RR map.

Seems utterly stupid to me

Matt82 · 13 Jul 2011 at 09:14

why would a generic map "ruin" an engine? generic maps have been applied to engines for years now.

Because generic maps are usually quite conservative by nature, but once you start tuning via generic maps and pushing components i can't see how that can end well in the long run?
