What we are working on is a 1990 Caravan... Factory 5spd T1 turbo van.. Which has recently received a stock Masi engine...
I had Rob (Boostbutton.com) work me up a calibration as the Masi engine was never paired up with a SBEC... only a SMEC.. He has been great!!! and he has done way more than I paid for to this point... So before I bother him to much I want to make certain the problem isn't on my end... The trouble is I need this van ASAP
Here is the deal..
a 2.5 T1 SBEC throws no codes.. No CEL SBEC unit from 90 shadow T1 auto.. fires right up run rough...
A stock VNT SBEC shows CEL but starts and runs.... never bothered to swap back to 2 bar MAP to see how well it might run....
throws
64(?) VNT circuit,
and 23 Charge temp.
The Calibration from boostbutton shows CEL Is hard to start and won't rev above 3K even when moving 15mph plus..... Based on VNT calibration with some mods...
via my OTC 4000 throws a
"unknown FaultFF" (IIRC flashed the CEL 66)
37 PTU circuit
23 Charge temp
Not sure if I did something wrong? Or? I figure before I start tinkering I should ask...
Adding the socket and flash module went well... Kinda... I screwed up a trace on the T1 SBEC from the van.. I had a spare SBEC from a VNT car... and put the flash module in that quite easily after learning a few things on the first try...
What I don't know is if I have something messed up... Or what I need to do to make the calibration play nicely????
While installing the engine I did have to modify the injector harness to reach the injectors so they would fire sequentially.. and extend a couple things here and there... but again.. no codes in the short time the van has run on the T1 SBEC calibrations..
Where would you start to make certain the problem isn't on my end?
