You'll get better longevity at the same power level with a blower on a renesis. Plus, they sound better. Weight and cost are pretty close either route. Personally, I think an E85 supercharged R3 would be pretty rad. I'd do it in a heartbeat if it wasn't for the fact that the performance/cost of properly FI'ing a renesis is mindblowingly awful.
Not trying to tell you that what you're doing is wrong, just posting in hopes that you'll consider blowing some money on a project I've always wanted to see :P

Ok so in other words a blower is a supercharger .... if that's the case i've actually been told , by relaiable sources, the opposite .... being that you'll get better longevity from a turbo, but to each his own i suppose.

Yep ..... from what i've been told the little hiccup we had at full throttle has been ironed out. So this week just some final tweeks and some dyno readings, then i'll get the car on sat which is when I fly in and then drive it back on sunday. So should hopefully have some dyno's to post or i'm sure he may post before i even get home

Well .... I have some news, Brad can probably elaborate on this but i'll explain best i can ...
Had the car running perfectly last week, then went to put on dyno yesterday or thursday and issues popped up. Seems like the Factory computer is interfering with the haltech, or that's what We're thinking, so at this point we're going to completely bypass it with the exception of the factory comp running the dash controls and everything up , requires getting additional sensors to run differently .... so looking at another week to get this done. Hopefully this will iron out any problems left and we can throw it on the dyno .... and most importantly i can get my car back before the summers over, lol , but it'll be worth it in the long run. More updates soon,

I had problems with the Haltech and the ignition on mine.....it was an older install and at the time the units couldn't read the stock trigger wheel..but the trigger never did seem to work properly.
I would get Haltech involved...and someone with a scope that can read the ignition pulses and see what the problem is

Funny you mention .... because he was thinking the trigger was the issue, but i believe what we're doing with the sensors would fix that. He's actually been on the phone with haltech about this , they say everything is right and no idea what the problem is. It'll get ironed out, though .... just gonna take a little more time, but almost there. Hopefully , he'll get on here .... i'm sure he can explain what's going on a bit better than i can.

Yes we are having a trigger pick up problem that happens as load and rpms increase. It showed its ugly head on Friday on the way to the dyno. I have been on the phone with Haltech and a couple other folks around the globe. I have another set of eyes that I truely respect coming in this next week for some more insight.
If you guys didn't know they moved the pick up on the series 2 and where the mark is on the wheel.
Have no fear series 2 tuning will be fully functioning soon. I have not been able to update much as I am working too much right now.
Thanks again for your support Brian.

Looks like we may have it figured out. Haltech software was set up to use a series one trigger, so Brad switched triggers and used a series one trigger . Seems to have fixed to issue in idle i'm told, going to put full load on it this week . Should know how that works out by midweek , but looks like we're seeing the light at the end of the tunnel B

As far as updates , I haven't talked to him about progress when pushing the car hard .... but he had to redo all the settings for the trigger wheel and use a series one trigger wheel. Again, so far this has seemed to fix all issues. I'll talk to him tommorow and see if i can get some more info. I'm picking up car in two weeks from tommorow. Wanted to give him some time with the car just to make sure all is good before driving it back to ohio. Looking goof at this point and should have some dyno stuff by the time i pick the car up.

Well the final damages for this are just the cost of the unit since my car was the first one. As far as time he has into this i can tell you it's a lot .... but now that he knows what needs to be done I would think future projects would be a lot smoother.

Absolutely. Just waiting (Admittedly a little impatiently
) for a final write upThese results have been a long time coming, so what's a few more weeks?

Okay Okay... I might get fried by everyone on here, but I have a question?...
I know the encoding for the S1 ECU is different, but does it run the power plant pretty mcuh the same? I ask because I was wondering about the possibilty of a ECU only swap....if we matched/reconfigured the pin out, or something similar, would it/could it run a S2 engine. I saw ASH8s long list of parts to do a S1 to S2 engine swap and there are some differences between the engines like OMPs and etc, but could it be done??
I wsh I had a wiring diagram and more tools at my disposal or I would just try it or really research it on hand, but that why I have all of you...

Hard to say but my guess is it would take a lot of work reconfiguring the trigger wheel, since that has been our main issue. I'm sure Brad would have a better idea .... but my guess is it would be tough. So many things seem to be different between the two series. At the very least though you'd need to rework the trigger wheel or maybe swapping that as well would just do the trick.

Yup .... and here's what i have. He got it on the dyno and said it had a small hiccup at 7000 rpms, at which point it was making about 185 hp to the wheel. He made a few more adjustments I believe to the trigger back at the shop which seemed to workout the hiccup at 7000 rpms. It's right there, close to perfect from what i'm told ... he asked for one more week with it. I couldn't get out there next weekend so I gave him 2 weeks and am planning on aug 24th. Damn i miss my car ! lol .... In the end I don't really know how much more power this is going to produce or increased gas mileage but that's not really the reason i'm doing this anyway. I would never spend this kinda money for the small amount of power i may get .... this is more about the turbo. No tuning , No turbo. That'll be next summer
Anyway, looking excellent at this point, almost there .... hang tight another couple weeks. I know we keep saying that but no ones been down this road before so it's a process. I think we'll be there for sure next post. B

Well .... Sorry to say guys but I have some bad news 
Today we decided to call it quits on our little project. We have tried basically everything and after Brad spent the afternoon on the phone with Haltech they determined that there's an electrical issue when the car pushed. Hard for me to put it into words, they could probably explain better, but basically the Stock ECU is not cooperating with the new ECU when put under full load, starts cutting out, etc. We have bypassed the stock ecu for everything except dash function, etc but it's still in the equation. Haltech Stated that they have in the past installed a unit that send a signal back to the stock ecu to trick it, so to speak , to fix the voltage issue .... but it's never been done with this car and so far anything done to try and "trick" this cars computer has failed miserably. May work , but I doubt it and i'm not willing to take the chance on this thing failing once i get the car back to Ohio.
Bottom line .... only way you're going to get an ecu to work on this car to do a turbo , supercharger, or whatever is if you don't mind ripping the stock computer out completely. If you plan on just racing the thing i suppose that's fine .... but not practical for me and not what i'm looking to do. I suppose you could rebuild the dash function with the new ecu to some degree but you're going to lose a lot of functions more than likely and that profect is more than i want to undertake.
We gave it our best shot ... 3 months of time ... unfortunately didn't work. Sorry guys, don't think there's going to be tuning for this thing without ripping the whole damn computer out. Wish i had better news. At any rate, Brad's putting the car back to stock and i'm gettin the car fri.
On another note .... if you guys have anything you want done with these cars I totally recommend Brad at rotary inspired performance. Guy really knows his **** and does some amazing stuff over there. If it can be done he'll find a way no matter what you're trying to do.
