VY ecotec in VP. Options?

[vlad01]

oh ok. so you only physically removed the ps and ac not altered any of the parameters.


guess my only concern is the injectors now. Should still run ok but with the EV6 response being a lot faster at lower pulse frequency I would expect some tuning will be necessary to get it right for the EV6 injectors.

Aren't there any injector parameter tables in delco euc? I 'm pretty certain with MS 2, MS 3 ecus you can enter injector parameters as well as other things like coil parameters etc...

[charlay86]

the delco certainly does have an injector linearity model, the parameters might not be in the XDF

[vlad01]

thatsnks that bit on info.

excuse my question coz I am a n00b at tuning, but can (if available) these parameters for the newer injectors be entered into the tune for the 808 without needing to do any real on road testing, meaning like set and forget and away we drive ?

If you know you are putting in the right data, yes. As the injectors are from a factory model you should be able to transfer that table if they are in the xdf (or someone can put them in the xdf). But in practice I would not expect significant difference, and would not worry about it untill you observe idle problems. You should be able to check the lb/min flow rates from the part numbers on online references, thats the main one to worry about.

"VS V6
0 280 150 973 (EV1)
20.21 LB/HR 207 CC/MIN 152.8 G/MIN 12 Ohm 3.0bar OP

VT, VX, VY V6
0 280 155 777 (EV6)
21.44 LB/HR 219.85 CC/MIN 162 G/MIN 12 Ohm 3.5bar OP"


can that pose a problem?

[Holden202T]

well its hard to compare when one is 3 bar and the other is 3.5 but i would be thinking that means the ev6 injector will actually be less flow then the ev1 injector when used at the same fuel rail pressures.

[vlad01]

yes it is, 14 lb @ 3 bar if I recall correctly.

So what do you think? can the flow table ( not sure on terminology?) be transferred over ?

oh btw this engine has it all complete EV6 and 3.5 bar reg. I also understand from various sources the EV6 is more lineal flow vs fuel pressure than the EV1.

[Holden202T]

i think the answer to the question is, it should just work ok, but you may find the fueling might be slightly off in places and the way to fix that will be a few logs and adjust the VE table.

[vlad01]

cool so the ignition map will stay the same correct?

So i recon I might need to get you to flash me an EEPROM to get me started.

Is there any guides to how I go about generating some logs? although it wont be anytime soon. Just want to get the engine running on a stand and make sure its healthy, still building the rest of the car

[Holden202T]

you will need to get one of VL400's aldl interfaces to allow you to log data, there is usb or serial options in the for sale section.
