if so, how do you set up the cold start to run correctly

I have the Holly Pro-Jection 700 on my 351 but it came with the car so I don't have an answer to this one, but let me know if I can help with anything else. I like it.... hasn't let me down yet. I could email a picture if it helps.

you program this fi unit with a laptop computer. you must have some knoledge of the vaious inputs. it dosent work well with a big cam though.

I am trying to find what number of enrichment I should start with
when cold starting, lets say at 50 degrees what�s your enrichment number ?
when cold starting my car it revs up and down erratically between 50 to 110 degrees
once over that temp the car runs fine.
Hi Keith,
Unfortunately I don't have the Holly software to load into a computer and check for you. It was programmed by the previous owner and I haven't needed to adjust it. I'm in Los Angeles, if you are nearby I'd offer to let you come by and check. Otherwise if you can send me the program I can get the info you need. I have the computer connector behind the passenger seat. Let me know if either way helps. Does Holly have any tech support?

if its the one that is adjustable with a lap top, connect the lap top and see what your readings and see what it is doing on the fuel map page. it sound lean so richen it up a bit. you can make adjustments on the fly at idle. if your in la i might be able to lend a hand.

Hi Mike I�ll start my car up some time this week and I�ll post my cold start settings.
I�ll note what happens at what temperature.
It is adjustable by laptop ,and if it�s lean how much is a bit. Holley says make adjustments then try it cold again.

I�m in Toronto Canada, Holley does have tech support but that was no help.
I have had this Di for about 2 years. At first when setting this thing up I would up & down the street all day Sunday, when stop a while then go at it again only to find that the settings that were ok are now not ok. That turned out to be a louse clamp on the supply side of the fuel pump, there are many many more stories about the long wrong road to getting it right. I have a program but it�s a DOS version, when and if I get the windows version I�ll e-mail it to you
i to have the dos version. what i have found to work the best is to watch the fuel map\grid and see where the dot is floating around, since adjustens are made on the grid. its best to use to people, one drive while the other watches the laptop. what cam do you have, mainly duration at .050?? i found my cap was to big and was causing vacuum problems to the map sensor causing a surge at idle.

Mike I couldn't find my patch cable. Untill now so I ran my car today and noticed that
at 45 degrees it ran smooth then at 50-55
it started to rough idle took a look at the 45 degree setting,it was 15 and 50 was 8
55 was 7 so I changed all the settings to 15 in the 50-55 up to 100 now it runs from cold
to warmed up with out any problem
I'm getting close
I've not used the Pro-Jection so I can't contribute to the discussion, but on all laptop-programmable F.I's, it should be possible to save your operating program to a floppy and MAIL it around. This's how my friend's Haltec EFI in CA wound up with a program from TX that cured his troubles...
