How do you expect E85 to alter things when tuning? The stock injector staging was kind of paired with the ssv/apv openings tuning around this with one set of injectors may prove challenging. Also with those big injectors are you worried about low RPM fine adjustability?
With a standalone he will be able to make a fuel map that will match valve opening/closing perfectly, it's not difficult for an experienced tuner.
If he is using Injector Dynamics then he has nothing to worry about with low RPM fueling (even though that is not very important in a race car, worst case scenario, you raise the idle.) I know plenty big power Evo and Supra guys that are running ID2000's and they are still able to idle like stock, and low RPM operation and driveability is not an issue.
I considered using 6x ID1300 injectors because they are better suited for E85 (they were designed specifically for alternative fuels), but I already have 6x ID1000's that will do the job just fine.

Posted earlier have I've purchased two ID1300 injectors. They will not fit in the P1 position as I was told by Tony @ T1, which I assume came from P. Yaw. Had to go out of town suddenly for 3 weeks, so have not seen the issue firsthand yet. So it seems that you cannot use 6 of them on a Renny unless maybe you can machine more clearance into the center iron - don't know if this is possible, it's just sounds like what would be required to get them in there. However, in theory four ID1300s could support 550 - 600 HP on E85.
The revised staging has already been used successfully without issue. Whether the factory did their thing for better fuel distribution or emissions I have no clue, but it doesn't have to be set up like OE to work. Well, that's still to be played out only using two injectors, but using 6 injectors it's no problem and I'm not expecting it to matter for racing purposes on just two. Tuning is no different. You just adjust the cell value in those specific rpm points as necessary. I was concerned about idle pulse width because that data still doesn't seem to be readily available on the ID1300, but was told it would more than handle only two rotors at idle.
E85, some of that ZOMG benefit stuff is generic and not necessarily applicable. If injected at the port opening there won't be much cooling effect on the intake air. I considered an extension between the the TB and manifold with the two injectors there, but then there are potential issues having a fuel laden mixture early in the intake process relative the manifold/valve configuration, the vacuum system, etc. that it seemed like potentially more problems than worth. E85 octane rating gets exaggerated quite a bit, it's not as high as claimed sometimes. The resistance to knock makes it appear to have a higher octane rating. Getting a cold engine started on cold days can be a challenge. There's potentially a few HP available, but on this engine it's all about small gains so anything is a bonus. Hoping that it will keep internal carbon build up at bay.

Oh on a side note, my engine builder has a lot of his customers running E85 now (he loves the stuff) and recommends this if you have a SOHN adapter or are allowed to premix (not familiar with your rules).
Can be found cheaper on Amazon I think.
Castor 927 - $10.95 : Maxima Racing USA, - Power Without Sacrifice.
Also if you are going to store the car for a month or more, the Lucas Ethanol Stabilizer works well apparently.

I pushed up to V13 and rebuilt my base map from the one Elliot provides in that thread. Thanks for the pointer.
Any other updates from y'all? To this day I've heard very little feedback from others usage wise.
I also recently released an update to Adaptive Tuner that displays and logs Innovate SSI-4 data such as Fuel/Oil Pressure. Additionally I have added display / logging of safety cut status.

Well we did find out one interesting thing with the Adaptronic after the install thanks to the MAP setup, the car will still run and drive when a charge pipe pops off But that is much better than getting stranded on the side of the road while you try and fix it, which is what happens when you blow one off with a MAF setup.
Overall it is a nice setup, easy to make adjustments, idles and drives great (out of boost), etc. I look forward to seeing the car dyno tuned.

Yeah we were just driving around the block testing it an went up a hill and that is all it took to pop it off due to a loose clamp. Once we fix a small vacuum leak and install new injectors then we should be able to get the boost control figured out and start tuning a bit just to make sure it is safe to drive to Dallas. But right now it drives fine enough to make it to Dallas I think. But he wants to have more injector before Kan does the tuning so we will install those first.

I will definitely be messing with traction control on the RX-8 though since the stock wheel speed sensors are nice and high resolution. Also the anti-lag thing, I don't know how you would actually set that up to perform an enrich/retard between shifts. The guide on the site only shows how to set it up for drag launches.
I suppose with a turbo if you do ignition cut only with the flatshift feature it would probably achieve almost the same effect. Just the fact that the throttle plate won't close in between shifts does a world of difference for boost recovery on its own.
Also new version of WARI was just released.
V14.000 (2015-June-12)
Increase current output on injector drive (will have the effect of reducing the deadtime so people upgrading from V12 or 13 will need to recheck their tune).
Added compatibility with NTK AFRM on 0-5V input, and AEM on narrowband input with external voltage divider
Added imperial unit output for Race Technology dashes
Added enrichment persistence on transient throttle correction and made throttle change detection more sensitive
Added output for SRT4 dash
Added option to close idle valve when engine is on boost (for 1JZ VVTI engines)
Added variable dwell time map
Added support for manual staging when injector sizes have been entered (VE mode or not)
