does the turbo have a the duel inlet manifold? as i was just thinking that the 2 lines could just be the same as.

I bet the 2 lines are for the "wing" action. Maybe there's a way to rig a rpm switch to some vacuum servos for that, but I'm not sure. Or maybe you can set the vanes to a permanent position, or use a completely different turbo without the variable vanes. Just throwing out ideas.

that was my thought, so you could use the 3200 and 3800 speed switches in the ecu as is. also while i've beed playing i noted the oe map sensor reads up to 160kpa which is about 9psi

what ecu are u using? if it the 2700 one there are 2 rpm depentant outputs. also an accel one (closes the fuel reg line for more pressure)

 

[jago]

ah now i see your issue. so what information have you got on it?

i remember you saying a lot of the loom and wire colours were the same, so i'm guessing the ecu pin out would be almost the same, on the 2700 ecu there is only 1 pin which is not assign'd in my diagram. that is B5 (3rd in on the top row of the 20pin connector as you look at the ecu.

can you trace where they go on the main engine connectors? then you could find out what they measure e.g switch or resistance etc... and how meny are there and what colours?

reason i ask is honda are good at using the same wire colour for say +5V and sensor ground etc.... so you could get an educated guess as to what they do under the manifold.

and with regard to the turbo vac box, i'll keep my eye out for one, but dont think the turbo ever made it over here.
