Eps big bore TB's

lj909 · 05-23-2016, 11:08 AM

Well i bought Dieselg37s and got them installed. I'm trying to get something scheduled with Seb. The idle gets kinda wacky even after idle relearn. Just to much air going in at idle. But other then idle it runs with new life! My butt dyno says more mid range! Once i get over to Seb and get some numbers I'll post them.

As for those 75mm maxima throttles, I'm not sure they'd fit under the bar. And for the wiring, the eps throttles come with an adaptor harness for the one side.

your problem is that the car just needs more tuning. i have successfully tuned over half a dozen cars to a smooth idle using these throttle bodies. a lazy tuner will not be able to recalibrate these. you are going to have to tune the mafs. most idle troubles result from a voltage imbalance between the two mafs in the tubes. with ecutek, its easy to work around this bc it has two maf tables, without it, the tubes must be clocked. your tuner really needs to know what he is doing if he is putting on big tbs and intake tubes, or your end results arent going to be as good as they are for other people.

I already have ecutek, i just haven't gotten over to my tuner yet. Thanx for the input.
