Hi

I have a 2010 SST EVO X and i started about a year ago to do my own ecu tuning.

I have an issue that has been concerning me for a long time, and could not make it resolved.

In Normal mode, about 30%-40% throttle, the gear box would rev up for about 1000rpm, during upshift. This is particularly obvious in 3rd - 5th gear.

E.g. on a partial throttle, the gear box would hang up at 3rd gear from 3500rpm to 4500rpm, during upshifting from 3rd to 4th, but what i would expect it to have a 'clear' and 'quick' upshift just at 3500rpm, then drop to less than 3000rpm when into 4th.

Can anyone please help or point me a reason?

Thanks a lot!

 

i've been digging in the forum about this rev hang issue, but most threads i found were for manual, and seemed to be happening both for upshift and downshift.

any updates/ideas for SST?

 

oops....

 

kinda sounds like your clutches are slipping but i could be wrong
