Which ECU with Termi slip on?

[Frustration]

I have the 2-1-2 slip on sitting here (complete with airbox cover and ECU) and have been reading about Fatduc etc...

Is the ECU that comes with this slip-on closed or open loop??

Wondering if i would still need / want the Fatduc?

[Chouch]

I strongly beleive that all DP ECU for Hypermotard are the same with different default setting for the A/F ratio.

I'm quite sure that DP ECU from 2-2, 2-1, 2-2 header kit and cams all put an end to the close loop.

Thanks!

Anyone here running 212 slip ECU and PC?? OR Fat Duc?

Not sure what you're asking, but I've got the Termi slip on with ECU and it rips. No need for a FatDuc. The bike fuels beautifully and doesn't stumble or backfire at all.

As I understand it, the stock ECU is closed loop through 4500 rpm after it is open loop. The race ECU is entirely open loop.

Thanks,

To be clear, I am wondering if the Slip on ECU is also a "race" ECU and fully open. I know the full system ECU are and understand the stock tune will be different between slip and full system, but was wondering if the slip on ECU was fully open like the full system.

Appreciate the replies and dont mean to be a goof but I couldnt find anything else here with search.

Yes.

The only closed one is the stock one. All others are full open.
