Big day today, it finally fired up and after a few seconds of loping it smoothed out and purred.

I didn't realize that I had not updated this thread in a while.
Truck is on the road and has towed our 5th wheel over the mountains a couple of times. Power is good and the 8 speed auto works very well. I'm still fine tuning the trans programing and just upped the boost from 22 to 28 PSI which looks like its helped bring down the EGT's. I need to swap out the torque converter as the stock Hemi one has too low of a stall and the Cummins lopes really badly when you drop it into gear. The truck side of things has been the biggest challenge and I still don't have a working tach and a few other systems but working on them.

Thats cool. Was wondering if you where out enjoying it yet. Know what converter you will use? Or will it be custom? Its always the truck stuff that takes the longest. my tach issue took several weeks to figure out. A simple 10ohm resister was the trick in my case.

Any updates on this truck?

Many of you have followed my ISB170 / 08 Dakota build for the last 7 years. Its been a great truck for towing our small 5th wheel all over the US and Canada from coast to coast.
Its time to build my "old man" truck and concede to an automatic transmission.
It still has to be unique so it will have the ISB 170 and an Allison 5 or 6 speed.
I just pulled the motor/trans from the donor van today and will completely rebuild it so I have a reliable base to work from.
I'm currently cleaning up loose ends on the Dakota before selling it to finance the new truck.
Here is a list of what I plan for the engine at this point.

Holset Super HX30, a bit more turbo than the regular HX30 that I have been running on the Dakota and love.
33% over on the injectors which is the same as the Dakota.
Steed Speed exhaust manifold like the Dakota.
Colt Cams does a stage 2 grind for these engines that is supposed to really "wake them up"
ECU tune to raise the RPM to 3200 and a bit more fuel like my Dakota.

This would be pretty much the same engine as the Dakota but with the larger turbo and cam regrind.
I think it should make a reliable and economical tow vehicle engine.

Is there a commercial gauge cluster that works with the ISB170 computer or on the CanBus or... Using some other gauge communication bus? Do you know how the bread van gauges worked?
Thanks! Gene

 

[EVguy]

I'm pretty sure the van I have has a CanBus dash. Its a one piece rectangular one.

Truck has been running well. The ZF8HP70 trans works VERY well once its tuned correctly, the low 4.71 first gear is great.
Had quite a time figuring out the belt routing with a PS pump, vacuum pump, alternator and A/C.
