Hi forum - I have a removable timing adjust style tuning box (not in right now)

I have found that when the box is installed, my clutch slips badly if the gear and revs are too high.
This tells me not only that the box works (I could feel it did anyway) but that the clutch is basically not rated high enough for the tuning box.

Impossible to get it to slip without the box :( - Thought the clutch was on its way, but clearly its fine in normal torque situations
Can anyone advise? I dont really want to go through the rigmarole and expense of uprating the clutch. At least not till replacement time.

Plus when you make modifications it starts getting into - insurance is a pain type territory.

 

Best, Lith.
 

Probably because it’s a generic box programmed on a new vehicle. And probably a boost/torque spike so the company can say it’s high torque 🤔

Custom Remap time !! However it does sound like a new clutch if you intend to do that. 
have seen plenty of remaps and tuning boxes that should be 480 nm ish but because there is a spike it gets sold as over 500nm. For a split second. That’ll always screw the clutch 

So they do claim they use custom per vehicle maps.

Imagine itll be similar to a golf GTI, but they offer a torque chart.
Not taken it to a dymo myself to confirm...

Not sponsored or anything,, just what I have. originally bought it for a vauxhall insigia 163 2L turdo diesel. Not sure it was as noticable on that thing tho :P
Sent it back for a new map. https://tdi-tuning.com/variant-datasheet/6436 is the supposed datasheet. I do note the data sheet is identical to the sheet for the equivalent golf GTI, so assume they used that

Hasnt thrown any errors for sure.
FOr sure dont think its anywhere near 480 Nm

Defo dont wan't any custom remaps for the same reason I dont want an uprated clutch....
for now.

Kinda a noob tho - I for sure take the chart with a pinch of salt.

Certainly, the graph is hardly precise.  Apart from anything else, the before and after power and torque curves don't cross in the same place.  The curves always cross at 5252 rpm.  

 

However, even in Mode 7, they only claim 310 lbs-ft of torque.  My old Mk5 Golf GT Sport 170 TDI made a dyno tested 330 lbs-ft with its Angel Tuning remap and never a hint of clutch slip.

I dare say though , in my defence, you had a diesel, and they often have uprated clutches due to the obvious higher torque a diesel will produce, for the same power.
Additionally, I suspect they will have a clutch list where they designate an existing part based on the expected output of the vehicle - obviosuly factoring in diesels and torque spikes.
My suspicion is that the 220 has been given a clutch that is only just good enough, e.g. 300 for my vehicle.

Again many large salt pinches. Doesnt change the reality of the situation that my clutch is either failing or just not rated high enough, possibly both.
Dont know all that much about best practices with those charts so apols, good to get some insight
