Aside from boost creep, the other question is how well closed-loop EBC works with the EFR IWG. The EWG I have on my 2863 is much more forgiving in the PID tuning than my IWG 2560 was, and it's also capable of doing almost a 4:1 ratio between max and min EBC pressure.

I talked to andrew about EBC and he said he was going to play with it soon. 1.4 has huge EBC changes. And you shouldn't compare EBC between pre-1.4 and 1.4.

now dyno again running like 5 more timing and a half point less fuel please :P

Fuel map needs work, yes. I will do a polished tune once I get the EBC valve into the system. I am going to stay very soft on the timing, though, since it's a 10:1 bottom end.

Did you ship the first batch of turbos on the GB with the 15deg clocking or stock clocking? I didn't look at the 6758 carefully other than to say, yeah big turbo!

Yes, CA91 too. Just one more motivator to get a low-compression forged shortblock into this thing so I can use the 6758 and E85.

They all went out as they were delivered to me, so no special clocking. I will write up some detailed instructions on how to clock the turbo properly.

Why not higher compression if e85?

Flex-fuel. The car needs to be able to run on pump gas when I can't get E85.

Makes sense. Looking forward to seeing flex fuel results. We need more tuning info on it for miatas.

I saw a 3D printed version of the manifold at Miatas @MRLS.
The pictures don't show how smooth the bends are and how nicely aimed they are into the turbine inlet.

Sav should show a short animation video of the rendering being spun around so you can visualize the 3D layout of the passages.

I almost can't believe it took 20 years for someone to come up with a cast mani like this for the miata. Seems to me the blatantly obvious solution for durability and flow.

I also got to drive an EFR6258 in the steep service road hills. (Thanks Gordon!) Very bottom end spool is similar to the GT2560, but 3000 RPM and up is quicker.

YESSS. This kit is driving all the turbo defectors back to the light.

It's a little freaky how quickly it snaps into boost from 3k+. I datalogged the '02SE going from 104kpa to 135kpa in 0.2sec, faster than I could get the throttle snapped fully open. It's a riot.

You are very welcome! It was nice meeting up, however brief. Glad you enjoyed it!

That was setup to be "soft" and the EBC was disconnected. I should have plugged that in for you

I want to see you get this working on the MSLabs MS3-Basic that's in the car, so I can copy things and have a hope of getting Flex working myself.

I was never a defector, as I've never had a trubo. What I wanted could not be met by turbos until now. I drove the snot out of my previous setup while others solved all the trubo problems. I enjoyed that setup and everyone who rode in or drove my car enjoyed it too.

I, uhh, did a thing.

I is very excited to fondle. If you need someone to break it in for you let me know. I'll find a 1.8 somehow.
