My Scanmaster Numbers

[LouD500]

Anyone care to look over my Scanmaster numbers?

'84 T-Type, stock turbo, stock injectors, cold air kit, 87 ECM with Turbo Tweak chip , 87 MAF.
After a good warm up, at idle I get:

O2 -- 710
AF -- 04
L8 -- 29
Bat -- 13.6
Int -- 128
BL -- 142
Clt -- 184
ATS -- 71 (I do not have the air temp sensor installed yet, so I think it defaults to 71 degrees)
R -- 800
TPS -- .50 (I'm guessing this needs to be adjusted to about .46?)
IAC -- 00
CC -- 101

As far as I can tell...things look decent. BL may be a tad rich, and the TPS a little high but overall seems ok. Car idles smooth and seems to have picked up some power over the stock ECM and airbox.

TPS needs to be .40-.42 key on engine off.

IAC is closed... Idle air is coming from someplace it shouldn't be.
BL @ 142.. Pulling fuel. Could be the "rich" you mention.
Idle @800, is a bit high. Is the car stock?
Headers cracked?
Vac leaks?

Car is stock except for the ugrades I mentioned. There is a slight exhaust leak at the exhaust flange going into the turbo. Next thing I'm doing is checking and replacing a lot of the vacuum lines. It's possible one of the headers is cracked...it is all original.

Those were the first numbers I got after hooking the SM up and installing the 87 ECM and MAF. After a few days of driving now, I get 10 or 11 on the IAC when fully warmed up at idle. I still have to adjust the TPS sensor down to about .42. It is currently reading .50...would this contribute to the higher idle RPM being that it think the pedal is slightly farther forward?

Appreciate the input guys!

After you fix any vacuum leaks/bad vacuum lines, do this procedure to get your IAC set right, hopefully this brings your idle down as well. Then adjust your TPS if it still needs to be.
