Title: Digiplex 2ts 500a swap for 2ts501a??
Post by: izzug otom on July 03, 2018, 09:24:23 AM: I just wondered if anyone hear would know if a digiplex 2ts501a would work as a suitable swap to test if there's a fault with my digiplex 2ts500a.

The 501a is from a 2002 Nevada carb, whereas the 500a is on my Cali 1100carb '95.

I can't seem to find any info on this anywhere.

Cheers, Izzug

Example, I put a digiplex from a Strada in my 95 "spot" 1100. the dreaded flat spot was gone and the gas mileage increased.
Many hae changed the carbs to Keihin's thinking the dellortos were the problem.
So, if were me, and I was pretty sure the box was bad, I'd give it a try.
*** just saw this. this place sells a unit that replaces either. So thinking you have a good chance the 500a will work.

It looks like Carmo is repairing w/same as what yours is mapped.

Post by: yogidozer on July 03, 2018, 03:52:57 PM: guzziology has those numbers, but the link shows a replacement digiplex that covers both models.
guessing the op has access to the 501a, both are carb. bikes. think it's worth a try. The Strada digiplex and the spot also had different numbers, and the Strada one actually worked much better on spot.

The link that Yogi put up, it is a digital repaired board. It should be the same timing as what you have stock.

yeah, but they are $434. I thought he had someone who had a 501A, he could try.
