4age to 4agze Daily

[88MKIII 1G-GTE]

I want your extractors... You know you want new ones

[Casey-G]

have a set of cusco ps headers going onto it, unfortunalty for you though those genies's you see in the pictures already have a new home. I can source you another set if you like? I'm not going to use an aftermarket ecu on my daily just yet, i done most of the wiring today, i just now need to plug everything in and hope that i got majority of the wires right.

mmmm ViPec V44, i want one too

[Mr_Flawless]

id use the link G4 over the vipec, yes i know they are the same thing, and there is probably a difference in price, but i would think that the tech support from reasearch and development, is better than support from receive and duplicate lol
not bagging anyone out, or taking a stab, just a personal oppinion

Nice to see people ripping though a conversion quickly with no majour dramas
Keep up the good work

[JP]

I've had perfect support from Ray and the vipec dealers on the three I own, Link took a month to get back to me on a query before purchase so I went with vipec instead. Same difference functionally but I prefer local support. If I was in NZ I'd go link.

You'll also find that the Adaptronic is about $6-700 cheaper to purchase than a link or vipec, install time is the same, setup/tuning time is slightly quicker on the link & vipec unless you have a gun adap tuner doing the job. The adap's also have a better interface for supported wideband controllers. (serial output from wideband controller plugs straight into the adap, no analog output required.)

Rays workshop is just around the corner from my place and he is a nice guy to deal with

Guys, its a daily, i have a project car, its getting a haltech e11v2 +a lot more shit.


This transplant in all seriousness was only a cheap way out for me to get the car back on the road, so far it has only cost me a couple of rolls of electrical tape, because i already had the gze sitting in a shed on a pallet.

no more crap about fully programmable engine management systems please, the OEM ecu is quite good for what it is, i do plan to play around a little bit mechanically with this engine, but only as far as compression, and boost levels.

Im sure there is an ecu discussion thread somewhere on this forum, perhaps discuss the adaptronic and viper stuff in there.

just friggen leave it.. plug it all in and drive it.. i'll get Jarred to post up his expertise in this thread for you..

don't go f**king around with compression etc etc.. you just need to do something with the knock sensor.. Jarred (terra) has got something sorted out i'm sure of it..

[TERRA Operative]

True, spinning the supercharger slower will just hurt performance.

I'm currently rebuilding my SC14 (Yep, it can be done) the trick is finding the correct bearings... They are available, I just have to get them from Japan to Australia, without having to buy a case of 200 of the things....... Maybe I'll talk to oldcorollas about sending some over..
The seals are easy to get, and there are a few interesting things about the oil used too (you guys should be using 30-40 weight synthetic engine oil, like Mobil-1 etc, NOT mineral based supercharger oil, like the Ford stuff. The Holden stuff is ok though).
Once I've sorted all that, you guys can be sure to find a thread detailing all the ins and outs of everything I've found out about these superchargers.
But I'm getting off topic....

Swapping to an AE92 MAP ECU won't solve the problem, trust me, I have a dyno chart from last week that proves that. I am also running a 7MGTE knock sensor, but that just pushed the power drop from 5500RPM to about 6200RPM due to the different tuned frequency of the sensor.

Really, the only way to fix this issue is to pull the charger or install aftermarket engine management.
I am working on a few ideas (bandpass filters for the knock sensor, voltage dividers etc) to enable the stock ECU to be retained, but at this point in time, it's just a matter of live with it, or go aftermarket or turbo.


On another note, while you've got the engine out, can I suggest the VERY worthwhile 3SGTE throttle body upgrade? It certainly makes a difference.

[Casey-G]

Its my car man, i am going to play with the compression, the higher compression should offset the loss in power from running less boost. Let me be, i just want my supercharger to last a bit longer.


Terra; i have read somewhere that running something like a 500 ohm resistor inline with the knock sensor has in some cases completely removed the power drop. Is there any possibility of this being true?

[JP]

a "quieter" supercharger does not fix the 5500rpm power drop, as it's still experienced when the charger is removed and turbo installed. I've got no idea who started the story about the power drop being caused by noisy/old/worn chargers.

The resistor inline is a trick the WRX guys use, it doesn't work on the GZE.

Here's an AE92 GZE ECU etc running a 10.3:1 compression 4age long engine with a turbo pushing 4psi, you can still clearly see the power drop, Witzl's was the same, so was Justin's although he was running 12psi with his turbo setup on an AE101 GZE long motor, ecu etc. it pushed 130kw atw before it flatlined at 5500rpm.

[Casey-G]

looks to me like fuel dropped off a little, and i have read of the resistor trick working on gze's.


and a "quieter" supercharger may not fix the false knock, but it will certainly last longer.



Also should add, if i cant fix the engine loom back to what it should be to make the engine run (hi fives to whoever done it in the first place...not) i'll have a haltech ready to get wired up in 2 days.

[JP]

That drop is NOT caused by fuel, you can watch the physical timing with a light and see it dialed right back when the drop occurs. Witzl was able to work around his with an emanage blue adding in ignition timing at the point the ECU pulls it all out.

[TERRA Operative]

Check out my dyno chart above, the air fuel is pretty constant, no sudden drops etc.

Interesting that it still happens with turbo, I never knew that. IIRC, it's been found that the knock sensor is maxing out (like screaming into a microphone), so I wonder what is causing it? Too bad we don't have a brand new crate motor to see how it acts....

[Casey-G]

We should just start trialing other knock sensors *new ones. surely the thread isn't an uncommon one.

JP you cant say that 17.8:1 AFR is good... was that just one a stock ecu? just curious as to why it drops so suddenly compared to terra's


I have a bit of a question about gze injector wiring, do i run ecu pin for injectors 1&2 to injectors one and 2 or do i run it to 1&3? as in firing order, from what i have found it looks that they are set up to pulse in pairs.
