I know how superior the TIII brain is, so would it be worthwhile upgrading the van to a TIII brain and wiring harness, staying stock or will the TIII brain run on a 90 van SBEC harness with some tweaks?

I plan to do that with my Shelby Lancer. I put in a '91 GTC (SBEC) harness in preparation for the TIII I'm putting in soon. Some connectors will have to be relocated to reach their respective positions on the TIII motor such as the TPS, AIS, and fuel rail connector. The plugs going to your current distributor would have to be relocated to reach the TIII cam/crank sensors which actually use the same plugs. I believe Jackson has actually done this before..
Yeah, I was told the HEP connectors plug into the cam and crank sensors with no issues.
I wasn't sure if the 90 SBEC harness will work with a TIII computer, and I know I'll have to run a wire for the coil pack.
I just really like the TIII computer, it seems far superior to the 8v counterparts.

It can be done, but what are you going to do about the crank sensor? Aren't you running an auto?
I could make a crank trigger setup so thats not really a problem.
My main issue is the TIII computer, it just seems miles ahead. The run better, drive better, get better MPG, the list goes on.
I will try my TIII SMEC cal and then go from there. Just trying to get some feedback on this so I can search for a 90 van harness. This could be my my winter project or just say f*ck it and go standalone, lol!

didn't you say you're going with a microtech?
I recently bought a crank trigger setup for TIII. If you like I can post some pics of it. BTW, I also have a '90 turbo Caravan harness I could sell you.

Yeah, you and I are kinda in the same boat. I also plan to run a 2.5L TIII on a stock TIII SBEC. I wonder how well it will work?? I think Cliff Ramsdell was using a Trimcal from FWDP on his. I don't expect I'll run my SL anywhere near as hard as he did though.
I'm pretty sure that '90 van harness I have is from an A568 van, but that shouldn't really be a problem for you. Even better if you decide to put an R/T trans in.
Cliff layed down some serious power using a TIII computer with a trim cal from Cindy.
Yeah, 90 5 speed van, no biggie, just modify the starter circuit.

Just get a 90 TI harness for your van. Its too easy to turn it right into a TIII harness from there. You only need to add two wires at the 60 way( charge-temp feed and ignition control#2) Even you can figure this one out
Am I right in believing the TIII computer is superior?

the wiring is not that bad at all. only things to think about before going crazy is the trigger and ignition setup. the rest is just soldering and routing the harness wiselyOriginally Posted by turbovanman
i'll post pictures when my engine bay isn't a mess anymore
why would you want to use your stock computer when you have a standalone doing all of it?

gotcha on the cruise, but my haltech can run an A/C
as for the tach, i haven't hooked it up yet, but there shouldn't be problem.
In many ways, I think so.
There's 2 parts to it - the code (which could be copied over to the T1 computer) and the DIS (which can't be run on the T1 computer). The real advantage to the code is the 3D tables - much greater flexibility in tuning than is possible with the 2D maps. The DIS advantages? Well, really just not having the mechanical device and the limitations on timing that go with it. I think a T1 computer, running the 3D code would work great...

Ha! I wish it was so easy. I'll do it eventually, though. You still want to try a 2D T3 approximation for your SMEC?
