how about four carbs on there?

 

Carbs 

 

May have a problem with my emissions test next MOT though. May also use a lot more fuel and lose power.

Alan mapped my 2.2 engine, which is now sat in your car, I now have a 2.5 engine with additional tweaks and had it mapped at NMS.   He spent a week mapping the 2.2 engine, NMS had only a morning. Therefore it was never going to be as good due to the time constraint.

Does that mean your ECU is perfectly set up for my engine? I can buy your ECU please?

 

 

the map was 241bhp and has been over written by the latest 270+ map, so pretty useless for you

 

Your car had a new TPS fitted a few years ago by Joey and the ECU has Fab's map on it (220-230 bhp)

 

I have the voltage written down somewhere for the TPS on Fab's map  

 

 

 

Does that mean that I need to steal Fabs engine now as well as your gearbox and seats? I'll add it to my list if so.

Unless someone has changed it the TPS should be set to 0.717v

 

So I get to use this thing I bought the other week?

I guess my arrow is pointing to the TPS? Just found out that a TPS is a potentiometer. How would I test this?

Also, my ITBs get soaked when it rains, that surely can't be good?

[fezzasus]

A bit of water injection never hurt anything (plus, consider the typical amount of spray a engine collects in the rain).

 

Why even bother with the Webcon ECU? Surely you could a proper standalone?

I didn't know there were other ecu's available for this system. That's another good option although sounds like I would have to change a lot and get it remapped anyway.

To be clear I can't promise that any ECU will work out of the box, however I was of the understanding that one of the issues with fitting a stand alone ECU to the VX220 was the use of a fly by wire throttle pedal. You've already changed that on yours.

Do you think all the existing sensors would work?

Starting to sound like a lot of sentences I don't understand. I may stick with the Webcon and see if I can take this Alan guy hostage until he sorts it.

[gaffer1986]

Think I've found him, if he goes missing for a week it wasn't me.

The throttle position sensor looks very similar to the one I had on a Webber alpha carb setup. Vocky should let you know which cables to check the voltage across. If it is like mine was just tightening the screws adjusts the voltage so it is a bit of trial and error until you get an acceptable reading. Have fun

[vocky]

the plug you need to access is shown in the lower section of your photo - the one which you can see with AMP written on it. (AMP is the manufacturer)

 

With the ignition turned on adjust the voltage at the Throttle Position Sensor (TPS).

 

To do this, connect a volt meter to terminal 1 blue wire and terminal 2 (centre) blue/purple wire of the harness connector.

The Throttle Position Sensor voltage reading requires setting to roughly 0.717 volts.

Once again, open and close the throttle a few times to make sure they are fully closing and that the voltage reading remains at roughly 0.717 volts.

Thank you, I thought so. I called Northampton Motorsport and they booking for 08/09/16 I may try and track down Allan and see if he would agree to help.

[gaffer1986]

This information is really helpful thanks Neil. What leads from the volt meter do I connect to the blue and blue/purple wire. Should I set the multimeter to ohms to measure resistance? What resistance am I likely to get?

[gaffer1986]

Oh, I see, testing the voltage, sorry. 20v dc will do?
