SMT6 again.....

[viceroy]

Ive just spoken to my tuner again and hes still having fun with the car.

Theyve installed the chip and the car runs, but then all of a sudden just cuts out.

Theyre trying to trace the problem, but if anyone has had anything similar and knows what to look for then Wed really appreciate the help.

Thanks

Andy? Ben? Anyone?

Id really like to have the car sorted before the weekend.

More info please.

Cuts out after what?

Throttle applied, left to idle, lights switched on...aircon on etc etc etc.

 

[viceroy]

Ill find out...

From what my tuner told me, its when idling but i cant be sure...

 

[BenR]

Shouldnt your tuner be able to solve this easily?

 

[viceroy]

Well hes a VW specialist, never worked on Renault before let alone a 172...Unfortunately we dont have Renault tuners here...but I trust this guy to be honest with me, and not screw me over

Hes taking the car through to Perfect Power this morning so they can put an osciliscope onto the car to try trace the problem.

Anyway, the car was cutting out randomly...didnt matter if it was idling, or being revved.

Is there anything strange about the crank signal etc which might be upsetting the chip?

 

[BenR]

the flywheel pattern is a strange one yes.

So I was told this morning...

While my car was at PP, they did map the signal, so should anyone want to install a SMT-7 onto the mk1 172, they shouldnt have any problems getting that info

My tuner and I did discuss going to a stand-alone system but for my purposes, its not really worth it...but Id love to get the injector timing working on the smt6...see what gains can be made there
