Wiring up Perfect Power XMS-L on a 20V

Postby muller on Wed Oct 15, 2008 8:58 pm

A lot of people are using XMS-L and like us have battled to get it working properly on the Toyota dizzy. Here is the idiots guide to wiring up the TPS and dizzy:

I'm using the same references as perfect power for the wiring (9/16 etc refers to the XMS-L wiring i.e. wire # 9 on the 16pin plug)

TPS (pin numbering as moulded on the TPS plug)

Pin 1 – 9/16
Pin 2 – not used
Pin 3 – 13/16
Pin 4 – 16/16

Distributor
(I'm numbering the dizzy wires from top to bottom as it is plugged in, i.e. 1 = top wire)

1 – 3/16
2+3 – 11/16 (i.e both pins 2 and 3 gets connected to 11/16)
4 = 2/16 and 10/16 & ground (to engine on dizzy side and chassis management side)

Though XMS works on the stock Toy dizzy it does not like it very much and it’s prone to interference. On the Locost we had no problems but on the Birkin we had endless problems with interference around 7000rpm. If the RPM signal on the management flickers to 9999 then that means you are picking up interference. We solved this by:

Double grounding the wires – not sure why but this is needed.
Using shielded wire and running it as far away from the dizzy, coil and plug leads as possible
Adding a little metal shield around the dizzy plug

Hope this helps!

Hi Anton

You refer to interference problems with XMS system... Does the same apply to the xms-l system?

Anton is referring to the XMSL here, but you will have the same issues on the XMS, which is basically the same thing. The XMSL is the "little brother" :)

OK so I have been underground in Stealth Mode for a while, but I've eventually started trying to plan my electrical side of things... I have pretty much everything, now its just starting to connect all the dots.
I have a PP XMS-L and a 20V and a Nice new battery :D

This is what I've come up with so far. Hoping I can get some advice to see if I'm on the right track.

I'm not sure about pins 3 & 11 & 2 & 10 on the big plug.

I probably read Muller's comments wrong "
4 = 2/16 and 10/16 & ground (to engine on dizzy side and chassis management side)
"

Also not sure if the fuel pump relay is done correctly.

OK so I got her started a while back, and I have a few days leave coming up :D so I can work on her.

Question is with the Perfect Power temperature sensor wiring.

Does one really need the output 16/16 (+5 Ext) to go thru the resistor and what does the resistor serve to do?
(I'm having trouble finding this 2K2 resistor and AC/DC tell me they are an electronics store so don't sell this "WTF" - MIDAS and AUTOZONE also can't help me. :cry: )
