Log looks good to me. Interesting looking at the afgs flatlining and the engine load being as low as it is. used to ej255 logs. Knowing nothing about your tuning process thus far, I'd try raising the timing or boost myself.

MAF(g/s) and Load is low because of the "half MAF" mod to bypass the 300g/s limit in the 16bit ECUs.

Yea I have the maf hack. I believe my timing was to low I raised it up a degree and started getting knock which I think on e85 is a little weird I've heard people running 28* on a 207 with e85 but looked at my idc and I was at 97% when I got the knock I think I maxed out my 255 I'm going to swap in my dw300 and see maybe I'll be able to drop my idc down a lot

Figure out the fueling. It's going pretty lean up top.

I have a very similar setup with a couple extra mods. Tuning with Carberry rather than the version 8 ROM. My timing is definitely quite a bit more advanced in the load cells you're seeing in your log. You should see noticeable gains for at least another 2-4 degrees if you can figure out what's giving you det. Very odd to see det on E85, I rarely see it before I stop seeing gains from timing advance.

I'm maxing out my ID1000s at 21psi on a similar turbo. VD is showing 400+ at that point. I'm running a DW300, but I'm not convinced that a Walbro is limiting ID1000s.

so i got my dw300 in and i just saw your post on maxing out the id1000's @ 21psi. the pump definatly helped out big time i now believe im in the same boat as you maxing out the injector heres a quick log i got tonight with knock still up top its leaning out. do you guys think it would be smart to cap myself off at 18psi and just slowly add in timing?

Log doesn't show AFR.

You sure you don't have a boost leak?

In any case, yes, I'd taper boost so your IDCs are ~93-95% ish and AFRs are stable. You don't need to cap your peak boost. You can run 24psi at lower RPMs if you want, you just need to taper it where the fueling can't keep up.

You may eek a bit more out of the pump by running larger wires both to the fuel pump controller and to the pump itself, but that's a lot of work. I've done it, but I did it all at once, so I don't know if there's real benefit. Realistically, unless there's a major problem, a DW300 should have plenty of headroom for id1000s.

yea my wideband serial to usb was acting up that night so i was going off my factory sensor since im on e85 anyway i figured it would be accurate targeting 11.5afr. but with the boost leak wouldnt i be having a problem with a rich condition open loop? im going to throw the tester on it tomorrow just to check it out since i did have everything apart to do the turbo plus weather by me the past few days has been 100% humidity and rainy

Factory sensor is before the turbo. The back pressure in the header messes up the readings big time. You can use the factory sensor to tune if you pull it out and mount it after the turbo. Pre turbo mounting, the O2 is only correct in vacuum to ~2-3psi.

With the 207 it's actually in the downpipe from the factory, I forgot to mention that
