View Full Version : New supra build running - driveability issues

09-05-2008, 06:43 AM
Hey guys, I finally got my Supra running! It is a full rebuild, still running the stock turbo and injectors for now, but i have a walbro 255 pump and aeromotive AFPR

I'm running the Maft-Pro with speed density, using a 3-bar map sensor feeding off of the stock boost sensor vacuum line (starts at the top firewall side of the intake manifold)

So far I have a code 24 (intake temp code) and 32 (HAC code), I know the 24 is normal, but whats with the 32? I definitely remember disconnecting the HAC... though theres a 1% chance I'm wrong lol

The car idles very loopy, goes up and down, but eventually does stabilize, there is major hesitation when I give it throttle, and the revs dip down and almost dies before shooting up.

I still have a driveline issue to debug as well before I can do more of a drive, and of course I forgot to have my assistant log the first one :(

Here are my settings, I removed the tables, if anyone wants to see them let me know.

I'm planning on adjusting the TPS enrichment, but I'm not really sure what the scale is...

I'm a little lost as to where to start, user tune? ve table? I just want to get it driveable enough so I can break in the engine before fine tuning!
