Holley tech service is awesome even on Saturdays ....... $550 shipped to the lower 48 .........

 

..... Still Available ...............

 

Did you ever get it running on your car?

 

...... Oh Yeah ! ..... Worked great ! ... what a blessing to tune compared to the erase and burn headaches of the OEM stuff ... I'm upgrading to the Holley HP to compensate for some major mods and to get a few more I/O's and options .............

 

What is the max engine size and modification this system will run?

 

..... No limits ... Some apps may require additional hardware that Holley offers ... i.e. : 16 or more injectors requires additional drivers .... there are base maps in their library for 502/502 Big Block Chevy engines ... and Alpha-N base maps for engines with extreme overlap camshafts (over 245* @ .050) ... Base maps for MPFI are available for engines using up to 50lb injectors and cams with up to 245 degrees of duration and Forced Induction ..... Its a VERY flexible/adaptable system and will go well beyond the base maps ........

 

........... FREE Shipping ! ...................

 

........... Still Available ! ..................

 

So with this, I can swap the harness (Maf car currently)/do a regular SD conversion, then this ecu is a plug-n-play?

 

..... Pretty much ... Just remove/disconnect your MAF ... add a MAP sensor ... plug the Holley harness in to the engine's sensors , distributor , and fuel injectors ... connect some power wires (run the main power and ground directly to the battery) ... load up a base tune and follow the instructions from there ... Installation and tuning instructions are included and are written in plain English .......

 

Assuming then that it'd work on a 305 and 350, with different tunes of course. If so, definitely interested. I want to keep my tpi when I go 355, also want SD on current 305 + the 355

 

...... This particular kit has a V8 fuel injector harness ... it will run any V8 with the early fuel injector connectors ... Tuned Port , LT1 , HSR , Ford , etc. ... harnesses and connector adapters are available to fit most any other application ... all you need to add is a laptop computer and a GM MAP sensor ........

 

Pm sent

 

Does this particular system run a wide band O2?

 

..... No , Its narrow band ... however , a wide band upgrade kit is available from Holley ... part # 534-197 ..........

 

Anybody know how this compares to the Gen 6 DFI? Only curious cause I know of one for sale...

 

..... Don't buy anything less than a Gen 7 ...........

 

Oh, thanks for the heads up! Question on your Holley...If I'd get this for my 91, how do I tie it into the body harness so all the factory gauges work? Car has a 383 with a T56, don't I need the speed sensor info fed to the Commander ecu?

 

..... The 950 ECU does not connect to the speed sensor ... just leave your factory ECU in place and wire the Holley to your engine and its sensors ... you can deal with the factory engine harness any way you wish ... I left mine in place for several reasons ... I did not get an SES light ....... Its really easy ......

 

..... Still Available ! ...........
