Hirsch mapped my Saab 9-3 but a slight issue....

I had to mash the pedal on the apex of a turn cos i knew it would be a few seconds before i was making my exit before the power actually came in.

I had the same issue with a Mk4 Astra Coupe Turbo I used to own.

I put it down to the fact that I was used to cable throttles fitted to high reving naturally aspirated cars and not fly-by wire throttle and turbo's. The split second of nothingness was only apparent when having a brisk drive along a B road though.
 
Been ragging the car a bit over the last day....

There's more power than the front wheels can handle at times. Mash the throttle in 1st and the front tyres squeel like crazy, and they're 225/45 17s, causing everyone to look around. Still get wheelspin in 2nd on full throttle with the front wheels feeling 'light' as they struggle for traction, and its only in 3rd than the front tyres grip without any wheel on full throttle. And all with default traction control settings!

Weirdly though, the car never feels hyper fast, only reasonably quick. Must be that linear power delivery....

I have similar power on 225/45/17's and I can literally launch it carefully in the wet with zero wheelspin... must be dodgy tyres as said :D
 
I'm good in the dry too when accelerating hard with 232bhp through 225/40/18s and most of the ton and a half odd weight no doubt going rearward :p
 
^^^ Sorry guys, I can't agree with any of you if you say that you don't/can't get wheelspin. Either the cars you've got have TCS/ASR and all other traction control devices known to man turned by default, or you're just not trying hard enough. I can spin the wheels of any practically any car with ~200bhp with the stock wheel/tyre setup. I used to be able to do the same with my 323i, and that only had 170bhp.

I just wonder whether the Hirsch map is confusing the car's ASR.

Wheelspin in second with 200BHP really does point to some duff sounding tyres - what are they?

Anyone can spin up in first by just clutch dumping at 4500rpm but spinning up in second is the realms of 'big power' which 200BHP just isn't, unless of course the tyres aren't up to the job.

I kinda agree with you. I find it hard to believe that none of you's have spun the wheels in 1st in wet with 200bhp up front. Anyway, that's a little off topic.

I can spin the wheels but you need to be trying to spin the wheels or launching very aggresively. In normal and even spirited driving it rarely ever happens.

And with 231bhp and 306bhp through the rear wheels I dont think either car isnt powerful enough.

I think your tyres suck.

Agreed, my LCR will only spin up in the dry if im deliberately trying to do so. I also turn ESP/ASR off as soon as I set off (which im sure fox will confirm, seeing how he dove into my car as I pulled into a carpark at a meet just to see if DSC was off!).
 
My car has no traction control. (only the V6 got that) I'm not saying its not possible to get the wheels to spin up in 1st & 2nd but its not a regular occurrence. (as i'm not daft enough to floor it in 1st, even though i mapped in extra boost limits to reduce the problem) Floor it in 3rd and there isn't any wheelspin with my current tyres. Back when the car was shod with pirelli p6000's i could get it to spin the wheels with almost no effort. (and that was when the car was running under stock power of 185hp)

Someone mentioned on UKS that the hirsch maps are on a 10 day free trial.
 
Just had a look outside. They tyres still have loads of tread on them. The rears are Toyo T1-Rs which reasonably decent. The fronts are something called Infinity INF-05. Can't say I've ever heard of that brand :D
 
Quelle surprise, you're spinning up a set of tyres that are a brand you've never even heard of. You could probably spin those up in a 1.0 Corsa if you wanted to.

Yep, that's what I've doing - I did say I had spent the last day ragging it.

The wheelspin I had noticed was launching the car from stationary at large roundabouts at full throttle, changing up to 2nd on the exit, flooring the throttle, then to 3rd, full throttle etc. All in the name of scientific research of course :p

And yes, the Hirsch dealer upgrade has a 10 day trial period. Go back within 10 days and they convert it back to the stock map.

Well yes of course if I drive to McDonalds' carpark, turn the ESP off and do a hard launch it'll spin up in 1st but launch conservatively and boot it through 1st/2nd and there won't be any. Your front tyres are just rubbish
