GR Supra 101: Routes to big power

Is the OTS E40 map a flex tune? Meaning if I get a flex fuel sensor, I don’t need to have it tuned to run different levels of E?

There is a flex fuel setting in mhd that you can enable on any map as long as you have a sensor

Just spitballing but would a flex fuel sensor be able to mitigate poor fuel problem with a (OTS) tune or does it literally just measure ethanol content?

Well it measures ethanol content to be able to adjust the tune accordingly, so I’d assume it would help if there’s inconsistencies in the fuel

I'm more talking about discrepancies with RON/AKI in non Ethanol based fuels. I've dropped my OTS tune down to 95RON to account for the 98RON fuel causing some timing issues. Would be nice if a it could automagically adjust on the fly.

Don't feel like I could get a real concrete answer from the previous replies for this / researching elsewhere so sorry if this has already been discussed 100 times;

Realistically what can I expect if I went RP65/Pure900 + HPFP + Injectors on 93 octane? I want to be in the mid to upper 500's on that setup with MHD sometime next year and want to pre-plan for it starting now.

Note; I have E85 access and already do E40 blending for my JB4 map, but there aren't a lot of E85 stations in FL and especially not along the highways, so for convenience sake I'd love to just run 93 on a bigger turbo.

From Pure’s IG, on 93 got 546 whp

ETA: do88 MERA, S58 injectors, Dorch DS25 HPFP

Remnant posted 628 whp on 93 octane with their new V2 kit recently. Stock fuel system

I just saw that, didn't realized they made a V2 of the kit yet, that's pretty crazy for 93 considering the other stock mount turbos can't seem to get past 550ish without a "kill" map.

Guess RP65 V2 will be the way to go then when the time is right unless something changes. Ty!

Wow thats crazy, i wonder how reliability has been on those turbos. Been considering a pure800 and ds25 + s58 injectors lately

I got in on the first batch a few years ago and i've put 15K miles on it. No major issues. WG had to be adjusted a few times as i increased boost to 35 psi. There was also a recall from the manufacturer on the coolant lines at one point so i had to change those. Other than that, tons of track time, hasn't skipped a beat.

I know all early issues have been corrected with the V2 including wg type, length, coolant lines and the turbine housing is 30% larger now.

I just saw someone on IG is posting solid runs and running a group buy on the v2. Surprised we don’t get one going here jk lol

Hey yall who are versed in the s58 injector/ hffp and a pure 800 or 900… the question I have is on 93 pump gas, are the s58 fuel mods needed or will I be able to achieve the same amount of hp with stock injection without running lean?
