Holley Tech has asked me to field any questions you have on this topic via email.

Thanks,

Thank you Very much Gentlemen

I run the Holley program on my MacBook Pro, I use a Parallels software virtual setup with Windows 8.1 it works perfectly.

Cool I didn't know that software was available

Haxby your Inbox is full so I will I ask you here.

I am running a 1997 502 mpi with a Procharger M3sc at 7 lbs. Motor is all stock other than Lightning Headers. I would like to upgrade to the Holley Hp controller.

Will I need any additional sensors seeing that motor came stock with a MEFI1. I do have an O2 sensor in my exhaust.

I plan on swapping out my 42 lb. injectors for something larger at the same time.

Originally was going to convert over during the winter but thinking I would like to go for it this summer. Can you pm me a price on HP controller along with any other items I will need to switch out my MEFI1. Thank you

Sorry, I cleared out my inbox. The ECU and harness kit comes with some new sensors, and a WB02 sensor, but it will also plug into all your existing sensors. I would definitely get some bigger injectors, and set up the fuel system with a conventional boost referenced reg. I recently helped the guys at Speed and Custom Marine in Florida with a couple Mefi to Holley conversions on procharged engines, I'm sure Scott would be happy to give you some feedback on his experience if you had any questions. The first one I tuned remotely on the dyno, and the second one they tuned themselves in the boat. It's a very straightforward swap. I'll pm you the price info, or just give me a call. 604-315-0570 Thanks, Alex

Good to see you back Haxor. I thought you got lost.

I got a call from Bob Madera yesterday saying my Holley HP system finally shipped! I can't wait to set it up and see the results when it gets here. Bob and Alex have been a pleasure to work with for sure.

On the install do EXACTLY as the instructions say ..... when you open the box READ the sheet on top ........ will be smooth sailing .....

There are some very good people out there ...... but Bob and Alex set the standard ....... I probably still hold the award for most stupid questions and Alex never wavered ........ I had a credit with Bob That I didn't even realize and almost 2 years later he sends me a check ......m
