EPS TB on boost
 

So my car has been at z1 for about a week now and Jon can't get the TBs to learn or something...typical?

Not sure about typical but I was reading some threads yesterday that said some tuners did not like the EPS TBs and had issues with them. I honestly am not sure which thread that was in though. If I find it Ill toss the link up.

I remember something about the tuners has issues with those TB's.

Sold mine, they are garbage

Have had mine installed for going on 2 years, no issues whatsoever. But, like others have said: some have issues, some don't.

I spoke with Jon back in October about tuning my EPS throttle bodies and he was reluctant. I ended up going with Martin at RS Enthalpy Tuning when he come up to Atlanta. I was originally tuned on Uprev with the throttle bodies, while I had no idle issues, I did have issues with revs rising when clutching in and throttle hang.

I converted over to Ecutek and now the rev rising issue is solved, but have idle issues when engine is up to temperature and slightly on the throttle hang.

Martin doesn't like the throttle bodies but he can get you squared away on either software.

Nobody likes the TB’s. No matter what
You won’t get rid of rev hang with those Tb’s
