What is needed to run with VEMS?

[GazzaG60]

yes it can.

the install for peter for S2martyn on his UR has the sensor in the top of the intercooler IIRC.

[Jamo]

Yes you can but why would you want to unless your manifold doesn't have the sensor boss?

The only issue with in the manifold is heat soak from the head to the manifold when the car is static but this can be removed with the use of a phenolic spacer.

I had one to install on my car but had to sell it because did not work with tall deck stroker. http://www.034motorsport.com/product...roducts_id=775

Just for ease of fitment. can use whatever sensor you want then.

last time I did this I removed the throttle body, stuffed towels into the manifold behind the hole so nothing could fall backwards into the runners, greased the drill bit, and ran a vacuum at the throttle inlet. no shavings left behind, worked very well.

Maybe thinking of changing to 1.8t sensor if my VEMS unit goes back for some tweaks I want to it.

How much is the OEM 1.8t sensor?

It´s around 32EUR.
I am also changing the sensor placement from manifold to pipe from cooler to TB. It´s made because at the manifold, there is too much heat from engine itself when the car is not moving or moving slowly and it starts to drop after moving a little faster.

Interestingly i have the same problem with heat soak with the wagner inlet, something i wasnt really aware with the OEM inlet manifold. So im installing the phenolic spacer from 034, as well as the 1.8T sensor on the inlet at the same time. Although not clear, there was recently a mention to a question Billman asked in the vemswiki about the 1.8T sensor and the responce was that on the 1.1.7x and 1.1.8x versions, the accuracy of temps is 2C and it is equal in PTC and NTC type sensors(PTC being the one our cars use and NTC the 1.8T sensor). I wrote that on vems forum and it appears that none of the tuners were aware of it, havent gotten a responce after i posted the link to the responce. In any case, i think ill have the 1.8T sensor placed anyway.

There is already reply for that.

[GazzaG60]

i have no issue swith the stock sensor.

Jamo IIRC the sensor that peter uses is a merc one.

[Jamo]

Pnanassy and A4kquattro did both recommend I go for the 1.8t from the off however I was covering the bases incase I wanted to go back to motronics

That phobia has well and truly passed and now i'm looking to integrate more of the VEMS specific functionality

Also Mattias has caused quite a stir here http://195.159.109.134/vemsuk/forum/...ic,1399.0.html

[GazzaG60]

what issues do you see that you feel warrant the upgrade. bad readings? the impact of these readings?

id like to see if i have any symptoms.

[Jamo]

I don't get any bad readings, it's the fact I didn't go to NTC to start with and now I will upgrade as part of my plans to completely cut over from motronics

[GazzaG60]

ok. i thought it was the old problem of readings.

is there a function specific to the NTC vs PTC equation.

There's a resistor that has to be removed from the circuit board, can be done as a DIY job TBH but I'm having other things done

[A80Avant]

i know about that stir, as i did the post, however after i posted the link with the explanation given to Billman, noone has answered, as well as their answers are irrelevant to my questions. Sure the NTC is better, but the question is since according to VEMS both NTC/PTC will have 2C accuracy, is there a point in upgrading to the NTC, if you are on the 1.1.8x version?

in other words, now that im still on 1.1.27 NTC is definitelly better. If i upgrade, do i need to bother?

A4Quattro was not aware of this fact,and i showed him the answer as well.

[GazzaG60]

good point. moving onwards from the aging versions is it an issue?

what you having done jamo. in normal mans terms not electronics. im not the best with the electron jargon.

IIRC i had the extra wiring for the EGT and WB02 in mine, 4 bar sensor. there were not many other options available then.
