the world famous evan tune! or atleast nc famous.

[Jeffy Dahmer]

planning on coming your way in the near future. 98 obdII vr6 gti (12v)

what kind of power gains can i expect to see, and can you mask over the wonderful secondary air injection CEL?:cool-up:

[evan@absolute]

Thanks for the love first of all. Sorry I don't think I can do it for you. I have had this discussion with myself a few times. I do not think I am going backwards to do those older ecus for now. I just don't have the time to study them. I have spent the last two plus years(read as 20+ hrs a week of my evening time in addition to hundreds of hours on the dyno. If you see me on here at night I also have 2 or 3 ecu projects open on my laptop as well.) learning me7 fairly well and the med9(mk5 etc 2.0t). I am now working with the tdi stuff which is 1000 times easier then the gas but still is going to take a lot of my "free" time this year. Then we have the 08 up 2.0t med17 fuel system to work on.
So for now with the forward direction of my business I have to look to keeping up on all the new stuff coming out instead of a few older projects.
But I really do appreciate you wanting me to do it.

megasquirt yo! :upyeah:

[Jeffy Dahmer]

leaning towards the bfi software designed by C2? heard any news about it? have anything you would recommend?

[Vampire Cockroach]

rode in my friend jordan's 96(?) vr with eip software and 268 cams. STOUT and surprisingly smooth for all the crap that EIP gets. :upyeah:

[gerich]

Glad to hear Jordan is still around. What's he up to these days?

[evan@absolute]

Well I had enough people wanting an alternative to the available mk3 vr6 "tunes"that I bought the emulator I needed to be able to make changes without constantly burning new chips. I also have been loaned a mk3 odb2 vr6 that is headed to be a track car or the scrapyard. I got the emulator working yesterday and this afternoon the Absolute "Rat's Nest" off road tune has been born!
Right now it's a stock file with sai,evap, cat and rear o2 eliminated. I should have an actual 93 octane tune done on the dyno as soon as it warms back up. Then looking for a "with cams" vr car if someone has one they want tuned.(I think I have one lined up but let me know if you're interested)

They will be available for sale soon.

That is quite a rat's nest.

[ipapo071]

Glad to hear that emulator is finally working. I am sure the break/dinner on Tuesday night brought some success as well.

In case you need to test a one "freshly rebuilt" VR6 (no cams) let me know. :)

I just put in the bfi/c2 stage one chip in my 96 vr gti last month. The car runs a lot smoother/quicker, and the codes for sai and emissions are gone. I would definitely recommend.

That post is way old.

I am running BFI's "PEM" with the cam/high compression software from C2 and although the car runs better than it did with Techtonic's chip, which was originally programmed for the cams alone (was not meant to account for the Mk4 headgasket), it was still running a little bit lean. I was at 14:1 with a 3.5 bar fpr, then swapped to a 4 bar per Evan's suggestion (he was even good enough to throw a spare one on during testing), and hit 13.8:1. Better than before, but the car is still on the lean side nonetheless. Optimal A/F for power is between 12.5:1 and 13.2:1 ( to Evan: I just read that again the other day in yet another source of information). I'm very interested in Evan writing software for my application. I just hope that there are other Mk3 VR6 guys that are also running bigger camshafts and Mk4 headgaskets that need the software as well.

You already know I'm down for it Evan. Let me know if there's something I need to do as far as bringing my car to you on the weekend to do some runs with the emulator. I promise I'll "shut up and color" while you work so as not to be any sort of a distraction. :boggl3y3dummy-ani:

also edit to mention to those whom this may not be clear to: I am not saying that BFI's chip isn't good at all, simply that my application needs some "tweaking" to make more power. I'm also running some other bolt-on modifications such as a "cold air intake", ported exhaust manifolds, "test pipe", 2.5" borla, stainless exhaust from Techtonics, and probably something else that I'm forgetting.

[evan@absolute]

Messed with this some more today and now I am interested to get yours back on the rollers. This old dog is bone stock with 212k on it. Once I tuned it the numbers were higher then yours up to 5k. Then your cams take over.
Here is just stock verses tuned
edit here is right dyno sheet......

That's a nice jump :cool-up:

edit I just noticed I didn't get the graph axis identical so the rpms are off. I'll fix it Monday.
http://i165.photobucket.com/albums/u80/absoluts4/rat.jpg

My car made 173 at peak though, right? Are you saying that it made more power lower in the rpms? The curve looks very smooth/linear. Definitely looking forward to seeing how it will do with the cams. :cool:

[evan@absolute]

yes your car made more power from 5k up. I can graph them together and post them if you want me to.
I am fixing the first graph so the axis matches.

[JNF1283MK3]

I would definitely like to see that, although that doesn't entirely surprise me though if the actual A/F is where it should be and the timing advance is similiar. My motor is sitting at 158k at the moment, but it has been less than 40k miles since I tore the engine apart and replaced the chains and replaced the cylinder head with a refurbished one (even before the work, my engine was pretty strong with about 170-175 psi of compression across all 6 cylinders). I think that I may have already mentioned that to you, but to anyone else reading this who might not realize how big of a deal that is that the VR you're tuning is already making more power, should get a better idea of why. I'm very excited to see how this tune is going to work for my engine! :shake:

Evan,

Just got a vr yesterday. If the motor checks out later on i have plans for 264/262 cams so whats up with a tune?

yeah, let me know when your chip kills itself and you have to ship it back to bfi for another. i bought 2 chips for mine and a friends vr and his went bad within two weeks and mine after a month. replaced it. and 2 months later it went bad again. im on my third... this last time i asked for a refund and they never replied and just sent me another chip.

evan, i'm planning on cams and a trip up to you shortly.
