Clutch Slip after Remap

[Grimola]

Hi All

I am sure this has been discussed in the past but here goes again......

Has anyone experienced clutch slip after a remap on a Peugeot, fiat or Citroen 2.8 hdi engine - only occasionally when using the extra power (over taking lorries on motorway and accelerating up hills). I guess it not a surprise as I have gained another 80-lb torque and 35bhp, but what I am wondering if the slip is due to the fact that my van (ex school minibus) has done has done 52k and is 11 years old - so the existing clutch is already worn with weekend springs - or is it because eth standard clutch is not man enough and replacing with a new one will not cure the issue.

I have tried sourcing an uprated stage 3 clutch from larkspeed but they cant supply one for my particular van so it looks like I can only fit a standard clutch

Thanks in advance

First thing did you look at adjustment clearance ,if ok then i would say down to rivets.

I would have thought a standard clutch would be fine unless your planting your foot to the floor in lower gears also without a strip down you don't know if your clutch is contaminated with or how it's been driven in the past

Thanks for your reply - the van is going in for a cam belt change soon so I will ask them to check the adjustment - if any as its a hydraulic clutch

I had the same problem on a fiat 2.8 . So had a new clutch put in and that was slipping too. The clutch is not man enough to do the job .

You have increased a 127 (ish) BHP engine up to over 160 BHP, which is quite a large increase. It is not surprising that the extra power is noticeable.

Sometimes a remap needs adjusting back down until a suitable point is reached.

I admit I did plant it when overtaking a lorry which pulled out in front of me when coming off a roundabout on a dual carriage way, and only slips when using the extra power, driving normally it seems fine. If I drop the clutch to test it doesn't snap back (like it did when I test drove the van before buying) in but the revs stay high and gradually decrease.

The chap who did a remap (celtic tuning and I have used him before and trust him) said he has done many M/h's and no complaints.

Going to see if I can make clutch last till end of summer.

Thanks for that - I feared that might be the case, will have the remap redone to an economy map as its FOC

Yes agreed - apparently it was only giving 115 bhp and 140lb torque (now 220ish)- will have it remapped for economy FOC

Don't forget to tell your Insurance Company you have modified it ... .. :goodnight:

Anything that is none standard is a modification. Even changing the wheels to alloys ..

Yet another reason why I will never have it done.
To be honest my 2.3 130bhp fiat is more than powerful enough for me.

I know - doesn't matter anymore as I am having it put back to standard, the extra power is nice but the van isn't built for speed (handling and rattles form fittings), not to mention the mpg dropping when you go above 50MPH.

I have a Fiat 2.8 with a Tunit fitted, and to date (after 2.5 years) I have had no problems with clutch slip. I do not change down and 'boot' it, but often accelerate to get by a lorry and get out of the way of faster (70mph+) vehicles.

I have a 2.3 and it was eco tuned.
the best for a MH, I think, it puts the torque low down in the rev range. Better to short change gears and smoother pull aways.
Think you would be better off eco tune.

I had bad clutch slip, but some numpty had routed the scuttle drain hose into the top of the bell housing. Plenty of meat on the plates, but rusted the plate springs which lost tension and the thrust bearing rusted solid.
Clutch change, all good now. 11k on the clock about 9 year old van.
Celtic have done work on a few of my friends vans/cars, nothing but good reviews.

I won't re-map for this reason, it's not worth the gamble just for a few more hp now and again. You also have to be careful using cruise control as this can gradually wear the clutch without you knowing.

How can CC wear a clutch?

That mirrors my experience exactly and the reason I will never have a remap again.I thought it would be useful having the extra power to overtake the HGV's on long gradients but in hindsight it was an expensive mistake,I am also quite happy tootling along at the national speed limit.

In a standard vehicle it probably won't but in a mapped van the extra power (HP) through a standard clutch can sometimes go un-noticed on steeper hills leading to slip. On a standard van the whole drive train is in tune but by increasing the power you should also fit a heavier clutch.
Just my opinion.

Had a remap a couple of years ago. Renault Master. I've got more torque so it pulls up hills better, a bit better MPG also. I think it depends whether you get a cheap generic remap or find someone who knows what you want and knows what they're doing. And yes, I informed my insurance company and they didn't have a problem. I suspect if you go to someone and say "I've got a 120bhp engine, can you make it 160bhp?" They'll say yes, 'cos they can, but I don't think it's just about the bhp.
Mind, I could be wrong.
