probably a stupid question but i wanna be sure before cutting up my ecu

the grey wire that says its the rev counter wire, says you connect to pin 9 or 21 in the ecu
it then says that the grey wire always connects to the pin that you fit into the ecu multiplug
21 for non air con cars or 9 fo cars with air con.

what i dont get is pin 21 is the air con input into the ecu and pin 9 is blank
as i dont have aircon i dont have anything connected to pins 9 or 21 in the ecu.
and from the wiring diagrams ive got nothing is connected to either of them anyway, and the rev counter takes it feed from coil/ign amp

any1 know what im supposed to do?

will call msd later but they aint open yet.

 

You can use any pin that isnt being used for anything else but...

I would use pin 21 as thats what MSD recomends

This keeps the installation uniform with others.

HTH

 

Cool

Oi si when you gunna sort that software out?

 

Stu,

Its nearly sorted.
I have added the ability to read chip files and view them in a formatted method including encrypted files.

I.E. instead of reading just bytes it will convert the fuel map to milliseconds and spark tables to degrees ..etc..

I will be giving it away 100% free including source code to keep the admin on this site happy.

 

Sweet. When do you recon? I need to use it now LOL
Need to make sure it's all ok before going to the rollers and wasting time setting up stuff I can do at home.

 

Stu,


It already works as a diagnostic tool/monitor.

As its you, PM me your address and I will send you a copy as it stands with a lead.
I wont be able to send it till early next week as I am not home till then.

All FOC of course

 

so wish i could get into this, but alas i need a car first
