vp ecotec???????

[emrmotorsport]

can anyone tell me what i need to put a ecotec v6 in my vp?

[padrickz88]

there should be a thread that hozy made ages ago, give it a search and it should come up

(id do it for you but i cbf)

[Morton]

A lot of patience. Me and a mate just got an ecotec running in a VR, and trust me, it's a kick in the c**t.

But if you're REALLY keen, there's already threads on this if you search

oh, matt finally got it running did he? Good on him...

[h0Ld3n`VN]

hmmmmm.. would a ecotec fit on a Vn auto??????? since sum1 opened up this subject for the millionth time

[centy]

yes the vn torque converter would bolt to the ecotec flexplate.

[immortality]

mechanically it's straight forward. some dicking around with the wiring if you run it on the VP wiring loom then then a tune to suit the ecotec in a 808 ecu

[lsprewell]

This might have been covered allready, and might sound rather simple minded but. Wouldnt it be a lot easier and wiser to use the original ecotec engine to ecu harness, and than just tap into relevent dash guages. I am putting in a VX ecotech box and engine into my VN and will be doing it this way. I will post a thread in couple of weeks as soon as I start. It should only take about 1week to do with myy limited time frame. Dont see the benefit of using the VN harness and having to use the old computer and old sensors. I would expect the VX ecu to be a ideal tune. With regards to imobilser, I will be using the VX key and just wiring it in permenately. VS exhaust header for drivers side and VN Y piece. Don't see any drama's at all. But we all know that in the automotive world, nothing straight forward ever ends up being STRAIGHT Forward, but I anticipate only minor issues. Fingers crossed.

Keep and eye out!

PS: I am also using the GM 4L60-E gearbox that comes with the ecotec's purely because I will be putting in Steering Wheel Padel shifters. Can't wait for that one. (More of a gimick, but still a bonus to have gear shifts at your fingertips, JUST IN CASE)

[immortality]

yes there are disadvantages to staying with the VP ecu, however there are some advantages. for starters your get rid of that horrible MAF sensor and run the standard MAP based tune. you will loose sequencial injection but hozy swears it runs better on group fire anyways, better bottom end like the older buicks. all other sensors are basically the same, just in different locations. also with the 808 ecu you have the option of any trans you like without having trouble code issues like with the ecotec ecu

[lsprewell]

Correct me if I am wrong but wouldnt I get better throttle response, fuel metering, and more consistent fuel pressure (in rail) compared to Batch Fire? Don't want to start a war on this issue, just looking at the most cost effective solution. And I can understand the Air Flow Meter issue, but I plan on having a couple of backups in case one goes. Also can anyone throw some figures on running the ecotech this way, they have around 150Kw of power standard I think, so how does that fair in Batch Fire, I don't see this affecting the power of the engine really but just interested to see if it does at all.

I appreciate your assistance too, I will keep everyone posted on the whole progress.

[centy]

i'm not sure but i was told that you would need a modded chip to remove the bcm stuff to get a later model to run right using the full harness pacakge.
I would expect a vs harness to be much easier to hook up to.

[skyper]

i would like to hear from u to on that subject

[Morton]

VS harness = bitch to do.

You have to change the engine loom, and the power loom, and the loom that runs into the car. This means changing the looms down the sides and back of the car, because they don't mate up to the VS forward harness. This means re-wiring EVERYTHING behind the dash, EVERYTHING in the boot, the fuel pump, door locks, power mirrors, door shut-sensors, and everything else imaginable. The whole lot has to come out and be replaced with VS units if you want to run a VS BCM and VS ECU.

Everything is so close to fitting, but just wrong Unless you want to spend hours splicing out the VS/earlier model plugs.

If you can do this conversion the way hozy did, DO IT, because it is MUCH more straightforward.

fuel economy i'd expect a slight loss but the ecotec ws better then the buick anyways so no loss overall i'd say, but who cares about that when chasing power. throttle response, well it was crap on the VS ecotec anyways, the way the TB has that ridge in it. would be better with MAP i think and a nice smooth TB. rail pressure wouldn't really be much diffference between batch fire/sequencial i think. Hozy would be the best guy to answer as he's had the conversion running now for a long time in his VN

[lsprewell]

Thanks for all responses. I have consulted some people I know involved heavily in EFI systems, and have decided to stick with the ecotec's standard harness. I don't see any real issues in wiring this up. In regards to the BCM, I will just hard wire the VX key. Seen it done before , not an issue unless you don't have the right key. It will be interesting to do some comparisons with Hozy, but is he still around, I noticed that it had (Banned) next to his hame!

[centy]

i got a vs harness here and it seems to be the same except for one plug.
Still gotta look into it more yet.

I'm getting ready to fit a vx donk to my vp aswell.

[h0Ld3n`VN]

so it wont be much of a problem??? vs-vy ecotecs arnt all the same arnt they?? would it matter which ecotec u use with a vn auto and vn wiring loom/ecu?

[TheA55hole]

Its not that hard on a VP..

Theres a guide/How-To by HoZy on the forum, It's worth a read if you are not fussed about sequential injection.

I still don't see the reason or sense in using the old VN ECU and harness on a newer engine like the VX's ecotec. The only reasoning for it would be if you can't read wiring diagrams or don't like air flow meters (Can;t understand why, Price used to be a factor but not really now). The more I try to figure out what benefits in using the old VN ECU and Harness are, the more of a headache i get. I would expect the ECU in the VX to be mapped pretty well for the ecotec

simple mate, because the 808 is MAP based and the ecotec is really just and evolution from the buick. MAP seems to give a better tune although more work is involved in tuning a MAP based setup. there is a reason why all the LS1/2 crowd get MAFless tunes done. also, most people with a little knoweldge and some basic computer equipment can tune the 808 from your home PC. you won't be doing that with the VX ecu. there are also only a handfull of people who have the definitions to tune the VS ecu and they aren't handing em out like cookies yet

[Cheap6]

There is another reason to stick with the VS or VT or VX wiring and PCM, and that is the rules for modifying vehicles in Australia require that the emission levels for the engine or the car, whichever is the more stringent, must be maintained after the engine swap.

If you keep the same engine management as the engine came with, no problem. Even if you mess with the tune, while strictly speaking illegal, you'll get away with it because it's virtually undetectable. Running a completely different engine management system is easily checked.

Using a complete VX spec. (and there are some engine mechanical differences as well as management differences) on a VS engine would be OK, as would a VX system on a VT or vice versa (same emissions ADR). Using VN or VP etc. management on a VR, VS, VX, VT or VX engine would not.

Different states may interpret the rules a bit differently but there is a national code of practice for vehicle modifications which most should now be applying. However, if you don't care and can get it past a rego. inspection...

yep, thats why every LS1/2/3 L76/98 running MAFless is illegal. yet it doesn't stop the majority of people doing it

[lsprewell]

I thought the LS1/2 crowd went MAFless because they are chasing that extra 10kw over MAF (If its there) and MAFless tunes cost a lot more if I'm not wrong. I really want to use the VX ECU because as far as I know it implements the 8192 Baud ALDL compared to the older (much slower) 160 Baud ALDL on the Series 1's. This is esentiall for me when wanting to display real time telemetry without using an aftermarket ECU or having a big delay. I really don't want more work either. Hmmm

THIS ALL MAKES SENSE TO ME.

Another reason why I should probably keep VX engine and ECU together. Wouldnt like to upset any of the authorities out there.
