good stuff, ill keep watching the thread for developments.
thanks

[lateshow]

just got mail from poland, the ecupinout says that VSS pin isn't used, how queer. But 10C for speed and 1A for fuel ??

[lateshow]

swinks: do you still have the same problem +
with AFR ratio, I think that is due to different ground level. You should get ground signal from the same place as the lambda set gets it. Only I have that problem that my PLX ets the signal from ecu's sensor ground, I cant use sensor ground for the UTCOMP unit or can I

[foxdie]

Mine and Atiks arrived today

If Swinks is going to pursue selling pre-installed kits to the club then naturally we won't, if not then once the issues have been fixed we'll import, pre-assemble and offer installation services to club members

[swinks]

Jason... you know...
I'm happy if you do sets for a club members. It's not a monopoly or anything that sort whatsoever.

Just made you aware of few issues you may face, and any other CVR4 member, after purchase and installing into vr4 vehicle. I'm expecting delivery of replacement UKP soon, so I will do some work on trying different sets and other options.

[foxdie]

I totally agree, myself and Atik are only in it to help our fellow club members...

If you wanna take lead, you know you'll have our backing

[swinks]

Right... update.
Good news guys! It's running smooth!
Video soon to follow. I need passenger to make video and for a next few days she works 12hrs shifts...

There are few issue you must be aware tho...:
1. Mentioned vss signal.
The only guaranteed way is to take vss signal off the gearbox. The is 3-pin black connector on the box, somewhere under throttle body. There are 3 wires:
- black
- black/white
- white/green
Signal is white/green. You splice into that wire.
2. Wideband AFR
For those with Innovate wideband stuff equation is:
AFR = 3.01*U + 7.35
where a=3.01 and b=7.35
Anyone with other make wideband analog output needs to find out equation formule from manufacturer or searching web.
3. Vacuum/boost MAP sensor
Remember, you have to flash UKP with equation formula for BAR. Later, UKP can switch display between bar or psi, but you HAVE TO put equation in bar. There are lots of equations written for different map sensors in psi or kpa so you will need to convert them to bar.
I have got AEM map sensor so mine equation formula was:
BAR = 0.86*U - 1.43
where a=0.86 and b=-1.43

That's all.

Just remember about first calibration. That's because default settings for vss are different that actual one from VR4.
For example: vss factor default is 0.200 meters/impulse where actual is close to 0.400 (mine was 0.398). That gives you false speed readings.
The same with injector default factor (liters/second) which is different that actual one.

Ohhh... and please insulate any not used wires from 24-pin connector. Some of them have either +5V or +12V output so any contact with chassis ground and your UKP is burnt.

Good job Tomasz, I've just sing in for a GB from mitsumaniaki.pl, UKP should be with me within few weeks (hopefully)

So far I find few very helpful guides how to fit that kit:

- here is one on ozvr4, is not exact the same kit (probably previous ver) but is give us some ideas

- here is foto story from Spiderek (miitsumaniaki.pl)

Tomasz do i just place an order through the link on the first post or do you want to do some kind of group buy.

i take it the price on the web site is US dollors $89

[swinks]

Oh.. c'mmon Adam. Fitting into clock bay is a dead easy. Need to search b&q for one "ingredient" that make it easy to make black display shroud (got mine from Polish Castorama DIY store)

[swinks]

No, Dave.
I was proposing GB due to quite high shipping costs. Anyone can do organize one.
Only reliable shipping (EMS company) is 100 PLN alone, regardless how many UKP we buy, oh... well, let's say up to 15. Typical shipping via Polish Mail service is not reliable and kaczart reported quite often parcels with UKP went missing when shipped abroad.

Yes I know, but you know front lights is still lain on shelf and waiting for some confidence to eventually fit xenons in them.

If you prepare for some waiting I'm sure we can sort something out

[Davezj]

just checked out the web site and following applies to the shipping cost.

1 item £30 total
15 items £35 total which is a massive saving on the total cost
even 5 would be a good saving.

is it really worth worrying about the polish mail service, is it rally that bad? if it is delivered via polish mail then it costs about £5 for a single item.

[adaxo]

The best mail service from PL to my home used to be my mother in law

[Davezj]

yes personal service is always the best

[Rixarena]

If anyone is organising a group buy then i would be interested in one of these.

Regards Sam

[Davezj]

Well that is 3 of us already.

[foxdie]

Happy to organise this for club members if they want. I've got 2 sat at home waiting to be fitted to a clock unit, what myself and Atik would like to do would be to offer these to the club as a complete package, pre-installed into the clock and ready to install.

If people are willing to wait a couple of weeks, we'll try and get something finalised
