Hey All

I current have a 97 R33 and have the following mods

Greddy frount Mount

3" cat-Back Exhaust

Turbo smart Dual Stage Boost controller

Aftermarket BOV

POD Filter

Catch Can

front Strut

Rear Strut

Im getting a Vi-Pec replacement ECU installed in a few days and just curious about after the install and tune of what sort of power figures it will make....With current mods im running about 11-12psi.....

How much more power do you think i will get from the ECU upgrade?

To be honest I dont think you will make that much more max power

but it should have a much higher average power and mid range :P

That is where you will notice it on a stock setup like yours vs a stock setup + ECU upgrade and tuned

Hope for around 190kw - 205kw

Although in light fo the fact you have both front and rear struts you might hit 212rwkw! :D

Oh I didnt see that! Definitely need a Full exhaust before you get it tuned

Who is tuning / supplying the Vi-pec?

getting it all done and tunes from Mercury Motorsport in Windsor QLD.

Also if i get dump pipe after cECU will i need a retune?

well its not really problem its just going to restrict the true potential of what the setup can produce

when my car was fairly stock the addition of a custom made split dump and front pipe really opened it up

the stock dump is pretty restrictive so its just going to limit your power / performance a little

No worries man - good luck with the tune - be sure to post back here tonight with the results and what you think of the new ECU

Will do but it will have to be tomorrow as They wanted to keep it overnight to do what they called a "Cold Start" [No idea what that is] in the morning so i should get it around midday or something tomorrow. Hopefully i will get a dyno read out and post her up to... I paid $1735 for the ECU and another $800 for Install and Tune.... is that a decent price?

Means they will adjust the tune on the car in the morning when it is completely cold to make sure it starts and idle's properly.

Price seems allright, however you really should have done that dump pipe before the tune as its going to be restricting it something fierce.

My expectations are 175-180rwkw.

Its a little on the expensive side - Mark at Godzilla does it for $2200 fitted and tuned

But if you are happy with Murcury and their Tuning go for it - I have never had anything to do with Mercury so I cant really comment

If I was to get a Vipec I would probably go to Godzilla

I am tossing up between a Vipec and a Haltech E11V2 at the moment

5 kw atw seems pritty crap to me my friend got hes subaru impreza wrx sti ecu remaped for like $2,000 and he gained 42kw atw and all he had done was a after market exhaust and a frount mount intercooler because the reseason u can get so much is because the factory ecu dose not no u have all the moderfications done to the car and it pulles back the power because it thinks the engine is going to get damaged so after remapping the saftey setting they beefed up the fuel going to the engine so they could turn up the boost and the guys said it was not a one off thing most car that they do gain 35-45 kw from it so a 5 kw gain seems pritty perfetic but i dont no it might just be the one u got

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
