Ribbon cable to memcal

Who has run a cable between the eprom and memcal to make eprom switches quicker? What kind of cable will shield from interference?

On some cars as little as 6"s of ribbon lenght is enough to pick up RFI. I've seen some switcher boxes that use like 18" long ribbons. If things act goody take it out and see if that fixes the problem.

I haven't done it yet to know if I'll get interference. I was just wondering if it's something that can be done reliably.

I tried this and it didn't work for crap....Kept shorting the ribbon and it got alittle better but I don't like marginal results...stay away from this your time is spent better elsewhere. Just my $.02

I also tried this with no luck

I'll probably revisit it later, but I got fed up with it and dropped the idea for now.

I have a ribbon cable and ZIF. Works fine at a length of like 9". At 18" I was having problems.

There is real potential for a problem. You might want to go really short, quality, or do something different.

Craig -

Have you (or anyone) gotten a harness extension cable (from harness connector to ECU) to work? I've been trying, but I'm afraid my hands shake too much for accurate pinpoint soldering on a donor ECU socket...

(I'm looking for a local elect repair shop)...
