[Dave]

MAP SENSOR ONLY (diagram)

[Dave]

Oh, you have to set your S-AFC for "Prs" or "Pressure" type sender.

if you want a copy of the manual, I have one in PDF format (in english)

Sure, u can try to send it to my email trac_420@hotmail.com and also what is the setting for my map senor? thank

[Dave]

.. I have no idea what the setting is for the map sensor, I think it's it's the up arrow pointing to the right (voltage goes up as pressure increases/vacuum goes down)

how come on the wiring diagram it says the white wire is not used, when it for the map signal to the s-afc?

[Dave]

sorry 'bout that.. (stupidness) I'll fix the diagram

--Dave.

I bought one also but havent had a chance to install it.

How did your tuning go? How much did you pick up on the dyno? Or did it just clean up your curve?

[93gtpdohc]

I have installed it, but i haven;t had anytime to play a round with turning it, because of college,and study, i haven;t even had a chance to finsh breaking the engine in, and i had it rebuilt in the summer, and converted it to 5 speed, but i plain to be driveing it in the spring, and get it all turned up, i would like to see some numbers like low 14's in the quater out of it with the turbo, but we will see, but i do have to say is the rebuild alone made a huge difference compared to how it used to go,

[Dave]

how'd the install go on that? was it pretty straight forward with the diagram I hooked ya up with?

if it's a good diagram, I'll see if Ben or any of the other owner/mod's want it as a "tech article"
