Vipec PnP for 94-95, 97-98, 99-00, 01-07 Wrex
 

We are your local authorised retailer, installer and tuner for Vi-pec ECUs. This ECU was developed by RAY HALL (Autronics owners would remember). The software is fantastic and the V44 PNP incorporates most of the functions necessary for a reliable and safe tune.

With Ray Halls invaluable experience with Autronics, the Vi-pec was further enhanced with a user friendly software developed by Ray Hall himself.

We are able to offer you the ECU at A$2500 installed and tuned. The Vi-pec incorporates a 2.5 bar map sensor upgradeable. This does away with the restrictive hot-wire afm. Vipec also has 32-bit calculations inline with Motec and HKS F-von V Pro.

Features include autotune, anti-lag, launch control and traction control in first gear. Canbus connectivity to other electronic dashes is also enabled.

how much for just the unit?

[QUOTE=redlib;566431]how much for just the unit?[/QUOTE]

This.

Does the $2500 include setting up the antilag, launch and traction control?

Does the unit also do rotational idle?

One would automatically assume rotational idle would be there with antilag!

If I'm not mistaken, this is a Link G4 with a different sticker. So I would like to see price alone too, for comparison

You are mistaken to some extent.

They are related but not the same.

That board is identical with the g4 pnp link ecu would like to find out the difference though if any

Isn't the vipec board made by link?

Quoting including setup and tune I think is very responsible. I would be asking other vendors for their price including tune. This is the total cost to drive away with a well set up ecu.

The price of the ecu as a stand alone unit is fairly irrelevant if set up costs vary a great deal.

I have been running this ECU in my V6 Sti for nearly a year now and it has not missed a beat!!

Some of us are quite capable of setting up our own cars, so why wouldn't I want a price just for the unit?
Also, some people may want to buy the unit and take it else where for install/tuning.

Guys I am going away tonight so replies will be delayed. Sorry. Will answer asap.

Yes I believe so. Will approach Ray Hall and see if he allows it.

I believe that if this happens, might have to set up a Vi-pec ecu thread in this forum.

Yes you are right, it is the Link board, but not entirely the same stuff on the board(not for me to disclose). Big difference between the two: software features and support on the Vi-pec is off this world. And you've got Ray Hall right behind this product.

The Vipec was developed to my specification and uses a lot of the features associated with the Autronic ECU. I wanted a ECU that was better then the Autronic in areas that had caused me and my dealers a lot of frustration when tuning. The Vipec works just as I requested, and as can be seen from this forum and other feedback the product is very good. If I had stayed with Autronic, and had not influenced the design of the Vipec, the Link product would not be close to the way it is now, which is a re-badged Vipec.

The Vipec comes with mine and the Vipec dealers support. If you want that support, then you have to pay for it.

Ray.


From the horses mouth.

RRP for P.WRX members is A$1950 who want to tune themselves.

re: Vipec Tune Results of WRX with stock STi engine
 

Hi Guys,

We have just tuned 03 STi Stock engine, breathing n intercooler mods only. Power was achieved @1.2 bar of boost maxing with 271.9hp.

We were about to go for 300hp but the standard factory 8 pound spring turbo actuator wiouldn't allow it. Time for an actuator upgrade I suppose.

Do your comparisons but Vi-pec rules!!!

[IMG]http://img89.imageshack.us/img89/6569/dsc00754k.jpg[/IMG]

Mao,

Silly question, can you explain the charts a little? It terms of correlation between the different lines on the chart please.

I assume its for different boost pressures? You have done a great job to get that power from 1.2 bar. As you well know mine only made 252 hp and 370 nm on 1.5 bar manifold pressure.

Also what ate the flat lines / dips on the torque @ 3800 and the hp @ 4500?

Cheers Pal !!!!

The dips were from 2 things:

1) On the avg STi, the actuator has an 8 pound spring. We boosted this car to 1.2bar after which the turbo boost was weening off. Basically, the actuator spring doesn't hold boost well after 1.2 bar. Even though we maxed out the boost duty cycle on the Vi-pec, the actuator could not keep up.

** Vipec allows duty cycle tuning of the solenoid, which means we can spool your turbo up earlier and more effectively. That's the difference between your last tune and the Vi-pec tune.

2) The variable cam caused the flat at 4600rpm, as you can see we tried to rectify that on the last run yellow line but the limitations of the turbo actuator prevented us ffom going on.

Basically, a HKS actuator upgrade is needed for this turbo, to get the most out of this engine.

3) The left graph is Torque and the right graph is HP. We did 6 runs for this tune and the base power of this engine was at 215hp.

I will show you the Torque and boost curve graphs on the comparison chart that would be consistent with your previous tune. Will be glad to share the info with you when you are back, but will hold back some of it in public as it is 'Vi-pec's n customers only' info.

Can't wait to dyno your car Simon. Will go for a nice break after that.

Mao

Vipec Tune on WRX with STi block
 

Hi Guys,

We did another Vi-pec tune today on a 2004 WRX with STi bottom end and only a VF22 turbo, with the usual cooling and breathing mods.

Max power at 291.9hp at 1.3-1.4 bar of boost (as usual, actuator was not holding well). Car came in with a poor Vi-pec tune at 258hp.

Comparing this to the previous tune on this thread, the difference was in the boost and the variance in factory actuator quality.

Below is the graphs from the initial to the final power run. (note we got rid of the flat at 4500rpm from the initial power run shown by the red curve!)

[IMG]http://img94.imageshack.us/img94/1372/dsc00785qj.jpg[/IMG]


Below is the initial power run with the Vipec already installed and tuned somewhere else. It ran only 258hp with a big flat from wrong boost setting at 4500rpm!:

Below is the result if 291.9hp after we tweaked the ECU:

That is good example of the tuner being the most important factor, nice work Mao.
On that WRX, what other mods were there? If you don't mind me asking, obviously TBE, but what intercooler, what injectors?

What AFR's is that running Mao?

AFRs are in the 11s and car had a Greddy Front Mount Intercooler that we installed in 2004 and a new Sti bottom end, while running a VF22.

Injectors were stock Sti 550s.

Don't credit me for this tune. it was all Warick's.

Well done Mao,

Warick has done very well. I might be able to get away from work on Tues night so I am wondering if I can watch Warick tune it, hopefully on the Wed?

Hey guys, it was my car that Warick tuned today.
Im also running cosworth 272 cams and springs and a Tomie FPR (not that the FPR matters)

Mods are the usual
*Apexi pod filter
*UEL extractors, uppipe and full 3" exhaust through to a 5" cannon (cannon to be changed in the future!)
*injectors
*walbro fuel pump

Im looking into a new turbo, still very undecided

This tune was on BP 98ron, as this is all i run in my new motor.

I was extremely happy when i saw the numbers once we sorted out a few little issues with the boost, as mao said, the stock actuator the weak point as always.

If anyone else has questions, feel free to ask, ill answer them as best i can.

Stoked with the car, she pulls hard and just keeps going :D

Cant wait for the weekend to go for a nice drive somewhere :3gears:

Big thanks to the boys at Evolution R!

U'll be always welcomed to sit in the car as well during the tune. Just let him get the base map done properly and u can sit in the car and watch the numbers on the screen.

Yes looks like wed, but latest thursday. Can't wait.

well looks like ill be booking the wrx in for vipec in not too distant future!

same here, i've been hanging out to replace my unichip

also i would like for it to be tuned for comptetion track etc, so for more response rather then the hp?

Yes you are on the ball here.

On every tune we do, we go through all the load cells and not just the tune at WOT.

No point having the power without the response.

Mao

I to am running a Vipec ECU, car is a MY99 WRX, and to say the least it has been a worthy upgrade, hasn't missed a beat.

We had the opportunity today to tune another V6 STi with a Vi-pec already installed in it.

The original tune in it had AFR of 9s! We revised the tune with the correct AFR the engine wanted and wala, the vehicle made extra 20hp, using 20 percent less fuel.

Although overall Torque only made 6Nm more, we tuned the engine so that the Torque was smoother throughout the WOT and also on overall driveability. By doing this, the effective Torque will be holding longer and more consistently, thereby increasing overall response as well. If you look at the graphs at 6000rpm, the inital torque was at 345Nm and after the tune, the torque was 365Nm.

We also fine tuned all the AFR and Ignition load sites to make sure driving response was better.

Welcome to the club. Good choice of ecu.

We have another Vi-pec to fit on another Subaru GD WRX.

We are not looking for high numbers here as the turbine is still stock But this will be a good reference for factory ECU tune vs Vipec Ecu tune.

Will be positing results after the holidays.

I am running Vi-pec in my rally car. I think I'm probably the only one in the state rally championship using it.
When the Vi-Pec was installed in my Rex a few years ago, no one had heard of it. At the time, Autronics seemed to be the ECU of choice (which is what I initially wanted). We had to go Vi-pec as Autronincs no longer manufactured PNP V2 boards for the early model wiring loom and besides, the old Autronic PNP's had a board mounted map sensor which meant running a line from the manifold to the ECU.

We are running a V4 engine, VF23 Turbo and the early model wiring loom. The car produces good power & torque figures with a 34mm restrictor and 98RON fuel, without running a "knife edge" tune. We could probably gain more power and torque if I wanted a hand grenade under the bonnet. We have done away with the AFM and upgraded the boost controller. The only other mod we had to do with the early wiring loom was fit an IAT(came in Vi-pec box).

The Rotational Idle & Anti lag are mandatory additions, both work perfectly.
At first I was sceptical as to how good Vi-pec would be. I'm happy to report that the Vi-pec is at least as good as any other after market ECU, especially for the price. (I've had Motec M400 in a previous rally car and installed M800 into a Celica GT4 as well.) The guys that have tuned the car seem to think the Vi-pec is pretty good too and I certainly have no complaints.

Karl

Just installed an AVO turbo, STi top mount and Walbro Fuel Pump on an MY03 WRX and put it on the dyno for a Vi-pec install and tune.

Vipec ECU was installed and tuned as well. Stock power was at 191hp with the Power Torque curves very wavey and all over the place. We installed the Vi-pec and achieved 264hp at 1.15bar and smoothed out the power and torque curves.

Below is the comparison graph of before and after Power and Torque:

Stock TD04 turbo?

As mentioned earlier, it is using an AVO turbo.

Customer supplied a used AVO turbo which I believe is based on the TD06 with their own housing.
