Hey all!

I just got back from Vishnu Tuning and had the emi adapter installed as part of my (now finished) stage1 kit.

WOW:eek: The throttle response is amazing:D :cool: I drove the WRX over the weekend with the stage 1. With just the stage 1 (and stage 0!!) the car would have minor hesitation as you go through the power band. All that hesitation is gone, nada, niet, zilch...:cool: the only gauge on the part throttle temps was my oil temp, which now runs around 75-80c instead of the old 90c. The power delivery is so smooth, you don't have to downshift, err umm, unless you really want to.. :lol:

Nothing but smooth blissful turbo spool'en fun. Just what I expected Shiv and his crew at Vishnu. Great job guys!!!!

you conversion to the blue side is complete..
[/darth vader accent]

this is also pointless

so odd how some little thing does so much.

I have been looking at one of those, but I am kinda on the fence as I am probably going to be upgrading to a utec.
I wonder why the TXS guys didn't think of that before releasing their unichip??

Oh well... I can live without one, but I am still striving for that smoothness. ; )

Good to hear you like it.

Glad you like it Chris!

Suddenly it becomes clear why we didn't release any higher-hp Stage packages until we finished such a device. Who knows, by next month, we may be up to Stage 8 :)

Cheers,
shiv

I'm intrigued...

My ONLY compliant w/ the Unichip is that it has those little hesitation 'fits' in the powerband where it's not totally smooth like the stock ECU was (still worth the gains and safety the Unichip provides though). Shiv or Chris, does this thing fix those little hesitations? Does it really fix all of them? Does it make the Unichip feel like the stock ECU again? Looking at just the Vishnu website, I'm a little confused, but a lot interested. In addition to the smoothness, does this also add part-throttle power? Also, I tend to leave my car in the low revs, IOW if I'm at 2800 RPM in 4th I'll shift into 5th ect. ect. What is that problem the site mentions about giving it a little gas at low RPMs?

stileg57,

It will not make the car feel like the stock ECU. The power curve is smoother than stock.

I drove to LA (~450 miles) in turkey day traffic :( yes it sucked. Ironically enough, coming back I bombed up Rt1 and it took the same amount of time as going down in traffic, but I digress.

At low revs, most (99%) of the low RPM hesitation is gone. The great part is, Shiv tells me that we can tune that out with the EMI adapter.

The problem mentioned on the website (I have not read it recently), happens to me at light engine load, around 3000 rpm. The engine will either surge a little, or hesitate a little depending on the engine load. It's not consistant and hard to nail down. If I drive like you 2800rpm, 4th gear, I don't see the problem (too much engine load) It's mildly annoying, but not as bad as with the hesitation you get without the EMI adapter.

You should order one, you won't be dissapointed.

Is this device compatable with a Link 44S ECU.

Or more specifically... will it do anything?

Thanks,

Dan

I really appreciate the fact that Shiv lists the downsides of the EMI right on the page. Not many tuners will do that so openly, and his honestly is going to earn him my business if/when I choose to mod. Hopefully by then a next-gen version will be even more refined.

I'm curious as to whether adding this device to a stage 0 would benefit from additional tuning after installation? Would not the maps be more stable, and thus allow for a better margin of safety and/or better performance?

It would be nice to smooth out the power band, but also to get rid of the misfire CELs I'm getting. I am pretty sure though that since they say it may not get rid of the CEL for every car.. that it's not going to work on mine. $195 more? Ouch.

edit : drunk should not have posted that

I was charged on the 16th.. I'd give the Vishnu staff a call to try to get the UPS tracking number. If you weren't charged until the 16th of this month (Dec), it sounds like your EMI Adapter didn't ship until that date. If that's the case, UPS is extremely busy this time of year.

I ordered the Vishnu Stage Sub-Zero (old kit with EMI Adapter, up-pipe, pulleys) on 20-Nov-2002 and received it one week later. I live close to Vishnu's location, though, so UPS doesn't take long to get it to me.

fart

I finally got this thing around the first of the year
now i get p0121 cels all the time
the service manual says to replace the tps when you get this code??

please help shiv dosen't answer on his own board.

please help shiv doesn't answer on his own board. Give Shiv a call during the week. He spends a lot of time dyno-tuning rexes, so you might not get him on the first try. Don't give up, though.

I can't recall which package you ordered. My (old version) Stage Sub-Zero was installed by Doug (one of the recommended installers) and I've never gotten a CEL.
