Just Boosted

[240GTR]

Ok we finished the full setup on our 1999 420A, and we have this little missing link peice thats supposed to fool the MAP sensor, a black box with a red and black wire, has anyone ever used this unit, if so, do you know how to hook it up ours came with no instructions? I think this is our main problem, the ecu keeps throwing up a tps low voltage code, and a map code, also when the car idles, you can tap the gas, and the vac will drop to -20, then creep back up to -10, and the car will barely run, keeps popping and backfiring won't boost at all.

Any ideas?

Thanks for all of the help

[Turbo 420a]

1996+ cars (OBDII) don't like detecting positive manifold pressure and will require the missing link in order to function with a turbo. Are you using the Hahn or Star kit? Here's a link to both kits instructions, hope this helps.
