Kgerrie157 Posted April 28, 2016 Share Posted April 28, 2016 Hi, I have a car with MDX321T, RCM Headers, Forged 2.5 SCDB, AVCS, RCM Induction kit, currently on TMIC with standard mapped ecu but getting mapped on FMIC on 6th May. Power was v420/420 on Toyo Sport headers at 1.4 bar, however turbo always wants to go past that and gives fuel cut, wastegate open etc, even with a !Removed! on ignition to reduce temps due to FMIC. Do you guys think it will run at 1.55/1.6 bar to reduce the overshoot on standard ecu? p.s the overshoot happens more with RCM headers. Is syveccs only option?

Tidgy Posted April 28, 2016 Share Posted April 28, 2016 Need to take it to a mapper that knows what there doing by the sounds of it, shouldn't be getting boost cut on a mapped car unless they have pushed it too far or has setup issues. For that sort of power then syvecs is the way to go, standard ecu won't cope, i ran my old hawk at 400 and the standard one struggled at the best of times.

Kgerrie157 Posted April 28, 2016 Author Share Posted April 28, 2016 What turbo, boost was that at? Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted April 28, 2016 Share Posted April 28, 2016 I see you say it hasn't been mapped yet? Or it has been mapped and then you added more parts? Want to make sure I've got all the details right before throwing random advice around. Quote Link to comment Share on other sites More sharing options...
