: DI/APC interchangeable between LH2.4 & 2.4.2??

Hello all!

Just a small question:

Does someone know if the DI/APC box is interchangeable between the LH2.4 & LH2.4.2??

Knowing that the LH2.4 is using a map sensor and the LH2.4.2 is using a temperature sensor...

Thank you for your help,

Nope.......the DI 'may' work APC control NO.

as for chips in your other question, SD advertises them for sale............

unfortunately not! :(

their chip is for the LH2.4 and not for the LH2.4.2....that's sad!

I have a contact with Abbott which can maybe help me!....let's see!

I don't know if it matters for the DI/APC side of things, but remember that LH 2.4 and LH 2.4.2 use different ways of sensing throttle position. 2.4 uses a TPS with two microswitches, 2.4.2 uses a TPS that's a variable resistor (aka rheostat).
