I noticed there is no plug on the end of the handheld remote. Is this the way they came or do you have the plug for it?

I just realized that the end is not showing in the picture.

Is a wideband Holley unit I use with my commander 950 compatible or is it an entirely new controller and sensor?

And what about my commander wire harness? Are they the same? Besides the self learning (which is a huge deal) is there anything else different between the commander and avenger?

..... No unfortunately , Holley went with a different wideband only O2S for the Avenger/HP/Dominator series ... they also changed the wiring harness for the three newer controllers from the one used with the C950 ... sensors are all the same GM style ... With the Avenger/HP there are 4 input/4 outputs to control more peripherals ... like water/meth injection , progressive nitrous , boost , and more ... Better datalogging ... sequential fuel injection ... distributorless ignition ... knock control ... drive by wire ..... I found a used Dominator at a great price , otherwise I was planning on using the Avenger for my new build ..... the Dominator offers even more I/O's plus electronic transmission control which I need for the 4L60E in my '87 vette .........

Very nice. I was so ignorant on the possibilities of an aftermarket ecu until I got my c950. I think if everyone knew how painless they are no one would even consider trying to use the stock ecu and all those chips. If anyone is thinking of upgrading I would bet any money I had you would never regret it. The stock systems are just clunky restrictive pieces of outdated tech. Just think of what a desktop computer was capable of back in the 80s.... And people still try to use those ecus and dropping hundreds of dollars to adapt them to their needs.

Glws i bet I'll be upgrading from the c950 next year about this time.

..... I was bound and determined to keep the factory ECU , so I struggled with trying to tune it with Moates Auto Prom and Tuner Pro for years ... when I finally made the switch I couldn't believe how easy it was or why so many , including myself , wanted to fight with the factory ECU ... it has so many overriding functions and emission tests/defaults built in that even if you get the tune perfect , on the 4th or 5th pass at the drags it would do its own unpredictable thing and lose a tenth or more ... there are just too many layers of factory code built in to the chips that are NOT parameters in hac tuning software ......... the aftermarket stuff is focused on the engine's operational functions ONLY ... no knock sensor test , no EGR test , no dump fuel to cool off the catalytic converter tests , etc. .............

I've going to install a ecu on my bird. I'm still trying to decide which is better for my allocation. I have a 350 vortech with the stealth ram intake and a procharger d1sc. I talked with holley about the avenger ecu and he said that with my supercharger it will have to be computer tuned. I have just came across a zz4 350 with forged internals. Which would be perfect for my blower. I might get read of the stealth intake and go with the carb style ecu on the zz4.

..... The computer the Holley tech was referring to is a laptop ... I would recommend this anyway with heavy mods or forced induction ... the handheld is intended for use with stock EFI or mildly modded combo's ... the carb style ECU with the ZZ4 won't work with forced induction ..........
