About my Powerchip piggyback ECU - Toyota Nation Forum : Toyota Car and Truck Forums

JetspeedCamry · 05-03-2005, 07:04 PM

Well, my next mod is done...a 6765 Powechip piggyback ECU. I was very sceptical about it at first, being a piggyback and it going on a 2VZ. I waited for about 1hr for them to install it, and then around 1hr for them to customise a fuel map and ignition table for me. As soon as I drove it out of the shop, the performance increase was already noticable. Much more torque than before, almost as far as saying..like the 3VZ. Fuel economy is about the same, if not better. Powerchip claims that the kW increase for the 2VZ is from 117kw to 133kw and as for torque..from 215nm to 242nm. I can definetly feel the torque increase. The guy said, because of the slushy auto..it won't be as impactful, but when I get the manual in it, itll feel alot more reponsive and snappy. It already does now with the auto!! so i'd can't wait to feel what its like with the manual!
Because of the extra fuel/timing, I have to run 98 octane fuel. Thats all good, as I usually run it anyways. The guy said, buy a bottle of octane booster, and if you need to run 91/95 octane, just pop in the bottle.
Tuning wise, it's possible to cater right up to a turbo/supercharge system. It's not a fully functional as say, a Motec or similar, but it definetly has the ability to change fuel and timing for camshaft mods or injector sizes etc. They said, if I need any tuning done because of addition mods, just to pop back in and I can 'borrow' there hand held coder for free and change whatever i need. Alternativly, I can buy the software and cable for AUD$500, and run it on my laptop so it can be tuned at any time. Might consider later down the track when I rebuild my engine.
All in all, this chip is ALL what they say it to be. No jokes..no BS..defintly brings out that hidden performance of your engine and takes away that "de-tuned" tuning that Toyota implemnts for the non-mechanic minded.
Very happy.

smt-6 wouldve been cheaper ($850 delivered inc data cable - cheper from the states... 350usd+shipping)

and you can map it to whatever you want to do... i had alook at the powerchip.. 139kw to 155kw for the 3vz

Thanks for that useless info about something that is in your opinion better. Next time you get a mod done to yours..ill point out the "other cheaper' options to you.

Terriyaki · 05-03-2005, 09:08 PM

sounds hot anyways, now it's like go go camy lol,i wonder if they have any piggy backs for a gen 4

terrastrife · 05-03-2005, 09:21 PM

you got lots of options for the 5s-fe.

i onlt pointed it out because your little review as no real question in it, so what i reply shouldnt matter ?

Glad it works. I really have to scoff at a 20lb-ft increase (161.25 lb-ft to 181.5 lb-ft), since none of the later VZ family make near that on tuning. But... If you're happy that's all that counts!

Try running regular gas. If you're *actually* tuning the ignition, you'll find peak power isn't made at the verge of pre-ignition on a 3vz-fe (so one assumes the same holds true for yall). I'd bet if they tuned it for max performance, isntead of jsut ramping it up almost to the brink of detonation, you can get away with cheap gas.

Ask MCE, Luckynumber5 or myself. Once you pass the peak HP on thestock engine (5500+) you can run atLEAST 20* of ignition advance without pinging. That's way too early for peak power, but the way toyota setup ours, they're laffably far from the point of detonation.

My very long drawn out point is try a tank of regular, if they were really power tuning, you've still got a bit of safety. (Besides... That's what knock sensor's are for. Unlike 1mz-fe's ours aint hyper, and apparantly they only break until you start messing with nitro/methanol injection and get a REALLY HUGE knocking LoL!)

JetspeedCamry · 05-03-2005, 10:25 PM

So you think that theres more to be had performance wise?? They did tell me to set the base timing on 10..as i had it on 14. Perhaps running a little more base might get more out of it??

The other thing i noticed was the HUGE loss of torque when i poped on the POD filter. Terrible!!
The stocky airbox and panel filter works soo much better.

i want it ! where can i get on for my gen 4 ?

Toysrme · 05-04-2005, 12:38 AM

No what I meant was I think they're lieing too you baaaaadly about the gains.
20lb-ft off a minor fuel leaning, and ignition timing? Like I said... I don't play with 2vz's, but just based off both 3vz models and 5vz's, there aint no way they "found" 20 lb-ft with a piggyback.

I also said it's your money, and all that's important is that you're happy.

Why can't I find any info on that online??? Even using google australia, and checking some australian tuning mags.

they used to be under fueltronics or something...

Wibbit · 05-04-2005, 03:12 AM

well i dunno about torque but unichip got 10kw@wheels out of my car, gotta be happy with that (for about a week!).
Jetspeed thats brilliant that you can retune it! youd prob want to do it on the dyno though because you want to tune while the car is under load. Good stuff dude, we can turbo together now!

you can retune the unichip too

just uhh.. how do you make more power under 5500rpm (i think thats the mark) without making more torque? isnt it relative to each other?

jackfrost1031 · 05-04-2005, 05:25 PM

I think only '90 and '91 V6 Gen2's had a knock sensor, at least in the US market.

but he did say: "117kw to 133kw and as for torque..from 215nm to 242nm"
yeh i know ive retuned the unichip a few times.

WTF you talking bout mate..u on drugs??

I said..thats the claimed increase...117kw to 133kw..and 215nm to 242nm....how the hell is that not relative??? I have no idea about what its actually producing..as I HAVNT DYONED it...and don't intend to either. I'm just saying...its a bloody good increase in power and torque..thats all.

And second..I'm giving my experiences about my POWERCHIP...so stop whoring my thread with your useless BS about Unichip and how it's this and that..when I have no need for such info..and nor does anyone else who reads my thread.
