Paging Tony to the trans assistance line

[oiler]

I was going to PM you Tony but I thought others might benefit from this.
I've finished the Ramjet install in a 93 GMC and all has went well.
The engine runs good and looks better.
The only issue I've had has been getting a proper tach signal to the original computer for shifting the 4L60E.
I got around that with the use of a diode but that's not the problem.
Both the owner and I think that the trans and engine could benefit from a more aggresive shift pattern and a earlier 4-3 and 3-2 downshift.
Have you had any experience with the stand alone controllers that some companies offer for the 4L60E?
They say they are fully compatible and adjustable but I've never really paid much attention to them.
Also what would be the best one to get, I have seen theat GM Performance makes one also.
Anyone that has any experience good bad or otherwise I'd like to hear it.
Thanks all
Jeff

the controllers I like are from www.CompUshift.com

easy to program & adjust with their own display / program box, no laptop needed.

The controller can be run with  a TV type cable to the EFI or carb...... or fed a TPS signal.
