Outer Limits 4x4 Board

has anyone juiced up a 1VD pump yet? im in the planning stage of some more power but the idea of being someones guinea pig is a bit worrying with a $30G motor. When the pump get done, im guessing the turbo may need doing aswell (unless it can handle 20 psi +) do any companies root around with variable veins?

AND, DP dont want anything to do with even getting a little more power out of their $1500 chip even though they assured me they would before i bought it, does anyone have the software for these to bump up the power?

im not going to bother with LCOOL as they are all tourers, most who dont even bother with chips on the 70 series.

being that the 1vd is a common rail fuel system. capabale of triple the fuel pressure it produces now and id dare say wastes alot of fuel. there would be imo no need to play with the pump to much. its all software related.
and being a vgt they are already pretty good but id say if your looking at running alot more boost you would need to convert it to a standard type wastegated turbo. weather the standard computer agrees with the change and runs though could be a different story.

really speaking all your power is going to come from more boost and injection mapping. so if the standard ecu can be broken into like an ls1 ecu then you could get that retuned but i aint to sure if its possible.

tuff75 cranked over 200 rwkw out of his but said the fuel pump was maxed out. i would like that sort of power all the time, without needing to turn the power down.

How did he crank his fuel pump up? 200rwkw would be in the range of 250-270kw at the engine? Which is a ~75% increase over stock, very impressive!

Maybe look into fitting a 200 series pump, you would think the twin turbo motor would have more reserve left in the factory pump.

AFAIK, Noones really be able to "Break into" the toyota ECU at this stage- otherwise 1HD-FTE swaps would be a HELL of a lot easier to do with 100 series engines.

Dont know how well you could go running an aftermarket puta either. Does anyone make one for a CRD diesel?

And considering the pressures that the CRD systems work at now, id be guessing that your piping and injectors would be getting close to their limits too.



I cant see why you need more power out of one of these motors in a 2wd vehicle... the stock workmate 79's will turn the road grippers into smoke without any struggle at all!

Chip it tuning chips are probably the units you want to look at, the software costs, but allows for a lot of flexibilty. It also allos for boost improvement.

You will probaly find the limits of the pump before long, then maybe the flow potential of the injectors.

Good luck, would be interesting seeing that 200rwkw dyno graph.

Possible to mount another injector like they do in the the 1UZ to make more power? Like a computer to run the extra one or splice it in somehow?

Not really- Diesels dont inject then compress it, they compress then inject at the right moment to make the boom.

Adding an injector would involve drilling new holes in the head.

just looked at tuff75 thread in the members section and the dyno print out says 212.3hp. with the aid of google search 212.3hp = 156.15kw

Yeah, i saw that yesterday too. no one around brisbane seems at all interested in getting more fuel out of the fuel pump.

should just dump the engine and put in a duramax

Maybe have a chat in this tread, there will be someone out there that can help, just might need to pony up the $$$ or start learning to do it yourself.

These guys reckon their chip is laptop tunable

Eh?

Commonrail's are not capable of 3x the stock pressure, nor is a fixed geometry turbo an upgrade.

There are many really basic upgrades for commonrail systems which fool the computer into increasing rail pressure, but they are a bodge. An ECU remap is the real way to get more power. Is anyone offering remaps for the 4 cylinder 2.2 L Avensis engine in Europe? It's half of the 1VD V8.

Isn't a remap just doing the same thing, altering injection duration, rail pressure and boost? This all allows it to make more power. Afaik, none in australia is doing remaps on toyota diesels, hence the amount of chips available. Cr pumps won't go triple the pressure, they can be made to have more pressure lower down, this in turn allows more fuel to be delivered, more power.

There is a limit as to how far you can go, you just need to improvise like the us guys do and fit another cr pump for more fuel delivery. The limit is your imagination and pockets.

There appear to be a range of devices, the cheapest simply increase rail pressure which increases fuel simply by squirting more through in the same injection duration. From there I don't know how sophisticated they can get.

so in other words im not likely to see change from 10G atleast

let me bring my 80 around, you can dump the engine in the front of it. I will then take it away for you free of charge so you dont have to figure out how to tune it

Have you spoken to steve at AMMS they are getting big numbers from 1VD s

That would be my initial thought too, talk to a Denso shop and ask them to look up the specs of the 2 pumps for comparison.

You'll likely run out of air before you'll run out of fuel.

why are you guys talking about pumps ????????????
what is the duty cycle on the injectors up to????????
thats where yon need to start not with changing fuel pump
its all about management
and thats what we dont have yet major management change abilities ie remap
a remap is generally much more than a tunit is capable of because it can run diferent turbos , rail presures etc etc

thats why duramaxes are so good because they can be remapped so easy

These motors will boost cut pretty early too and turbos run out of efficiency too. You put fuel in last. Get it to breath (ie much better intercooler and exhaust) The factory cooler is shit really
Northside 4x4 have unichip capabilities with these that work well with boost cut defender unit also. You can then piggy back a chip on top of the unichip if necessary.
I can not remember the power they ended up getting out of theirs but it is all you would need (with engine safety still good)
