TPS adjustments, unclear on voltage readings.

Just looked at my pinout, and I do have the VSV1 output which is an intake air control. Mmmm, maybe Ill Ebay an upper half of an NA setup.

What about the VSV2, which is a fuel pressure up valve?

VSV2 modulates the FPR's vacuum signal. The Cressida had it too... Most vehicles have one and you definitely want that in place.

OK, so I just picked up an NA intake.....still need to find one of them VSV valves, but I might be able to scour one up here at the house.

Im about out of money now for this project at the moment, got some dollars to put onto a T56 for my Volvo project. I should have enough parts to get it up and running far better than before.

Maybe anyone got a couple of them VSV valves kickin around?

Heh, I've got a bucket of misc VSV's somewhere (probably in storage as I haven't seen it in some time... that or someone snagged it). Any 12v, two position VSV will do though. Just hit up a junk yard and grab a few VSV's from Toyotas, Hondas, Mercedes (Mercedes has a couple which only cost about $30 new... sorry, don't have the part numbers handy); You'll be looking for one with three nipples (one is for the vacuum constant source, one is closed when there's no power but opens when there is power and the other it normally open and closes with power). Typically they'll have a vacuum line running to two nipples and a breather on the third. I don't have time to go hunting, but if I come across one which will work I'll let you know... Still probably going to be quicker for you to just hit a salvage yard and grab a few for $5.

Cool, I am headed to the yard to test fit some stuff, so I head over to the Toyota section and check it out.

Thanks for the reply.

After reading up on the ACIS system its really cool, and I think Ill benefit 100% from the lowedn torque when Im out wheelin....I like to motor through second gear in lowrange and grunt though the trails, I have always lacked wot pulls from like 1500/2000 when under load. Doing some more searching brought me to TB swaps....I see the stock is a 60mm for a 3.0. Volvo has a 2.8l inline 6 that uses a slick 65mm throttle. Im a fabricator by trade so working the shaft to install the toyota tps finger and making an adapter plate to fit the Toyota tps should be pretty easy. If not, the stock volvo tps is a potentiomter, wire that in and use a switch like a nitrous activater for the idl pin. I would just have to setup and see what the voltages range from using the Volvo tps. But I think I can mod the Toyota unit on there.

Im also looking at the Pacesetter 5m header....I think I have room between the frame and bellhousing to get it in there.

I seen a guy use a TB from a newer mustang one of the daul butterfly ones and modded the n/a Y piece to fit it.
