    Ribbon Delete

    With the closing of R&D there apparently is no longer a source for a ribbon delete kit for 2018 GP1800's or any other SVHO from 2018 and up that has the plastic intake. Is current thinking still that it is a noticeable improvement? I notice Riva does not list it in any of its upgrade kits for the earlier years, it is available but not included in the kits. Makes me wonder if its really worth it or if there are other drawbacks that have been identified over the years.

    When I replace my Vipec ECU on my Riva stage 3 FZS 09 with stock ECU and Maptuner, I ask Jesus Garcia to make me a map to fit to my configuration. He told me to put my ribbon back on because is better as keeps a better fueling balance between cylinders. I have no power loss as I run 8350 rpms with 15/23 Skat Trak and I feel more safe because I blew my #2 piston in the past.

    I did do ribbon delete on plastic mandifold... every time I checked my plugs 2 n 3 were leaner than 1 & 4, even with afr at 11.8. I went bak cast mandifold n put ribbon back in, now all 4 cylinders r equal... Jesus said same thing to me too leave ribbon in

    Doesn't Jesus work for Riva? So Riva is saying it gives you a solid 1mph increase but Jesus is saying to put it back in?

    The other thing though Riva shows both the 2017 and 2018 both go the same speed with same mods even though the 2018 doesn't have the ribbon delete???????

    That is why when you get a tune from Dean, he will ask about the ribbon. If it has been removed, he will add even more fuel to #2 & 3.
    Ribbons are for . No feminine tunes from Dean's Team.

    If 2 & 3 are lean and need more fuel, that also means they are getting more air than 1 & 4, which therefore means 2 & 3 are making more power than 1 & 4, not necessarily a perfect thing and definitely not balanced.

    Im pretty sure when they write the maptuner tunes they monitor AFR on all 4 cylinders and write the tunes to compensate for the ribbon being removed

    That is correct. Jesus monitor each individual cylinder on the dyno when he makes the maps. Thats the only way to do it properly since there will almost always be imbalances due to the shape of the intake tracts and different temperatures between inboard and outboard cylinders.
