Just picked up a 2016 1000F leftover. The dealer said they would install the current ECU. When I went to pick up the bike the ECU just came in and they did install it. The bike is super smooth BUT no speedo, TC light is on full time, and after 15mins riding the F1 blinks and the check engine light stays on. My dealer has been great and is going to call Suzuki Monday AM to either order a new ECU or resolve the problem...Anyone had any similar problems?? I love the response with the nes ECU and really don't want to go back to the 2016 ECU.

I assume you mean the slightly later ECU - it was only a minor change from the first ECU to fix the surging on cruise. The current ECU (L8) is a completely different ECU and is incompatible with a 2016 bike.

What error code is it giving?

are they really that different? I was reading and assuming it was just leaner fueling. Interesting to know.

You have probably done this, but if not check they tightened up the battery terminals.
A charging voltage check would be good idea as your fitted battery is original 2016 stock as well. Does the headlight flare up a lot when you rev the engine ?

Completely different, different wiring harness.

From what I understand the 2016 GSX-S1000 ECU is physically similar to the Hayabus and the K7-L6 GSXR1000 ECUs.

The 2018 GSX-S1000 ECU is the same as the 2018 GSX-S750

F1 flashing and check engine light on after about 10 minutes. Also TC light is on. No speedo. Dealer is going to call Suzuki today. I will refer him to your remarks.
Thanks

Sounds to me like a speed sensor error, c16 (front sensor) or c91 (rear sensor). I never trust the dealer 100% so I would check the code myself first.

how long did it take them to install the ecu....the physical work is awkward enough but then all the sensors and servo motors i'm sure need matched / calibrated / learned to suit the ecu.
FI light is probably the exhaust servo
TC is likely the wheel sensors
I've not seen the software dealers use but I heard its just a box ticking exercise to get the ecu to see them.

In the manual it states the F1 and check engine are fuel injection issues. F1 blinking and engine light on bike will still run. F1 on and Check engine blinking bike will not start. Took him about 75 minutes. The ECU is under the tank on the 1000F. I sure hope he sorts out the problem because I love the bike. shifts like butter and the engine and throttle response are ultra smooth. Last bike was a FZ-09 and it has it all over that bike. I don't even notice the 40lbs extra weight. 1000F is very well balanced. My only complaint is the gearing...definitely needs an 18T sprocket and maybe a couple of teeth less in the rear.

Another thought!
As well as there being a difference between the 16 and 18 model. Could there be a difference between the ABS and non ABS model even if they have the right year???

This was my thought exactly. I know for a fact that the software for the ABS model and the non-ABS model are different even in the same 2016 ecu. You cannot stick and an aBS model in a non-ABS model, it will give you all sorts of funky errors on the dash but the bike will still run. I have personally tested this and what he describes sounds almost exactly what happens. I have an extra 2016 ECU.

The Hayabusa ECU was the same one used in the GSXS from 2016. When you search the part number for that ecu it comes up for both bikes

Thanks much for your comments. I passed them along to my service manager and will post the fix when he resolves the issue.
Anymore please reply.

Not necessarily, FI and check engine are ECU errors, not just Fuel Injection errors, and include things like speed sensors, Tip over sensor etc


Have a look at what ECU part number it is, ABS and NON ABS are different

It was the incorrect ECU. Suzuki sent the non ABS rather than the ABS. The service manager sent them the SN of my bike which should have told them which one to send. New one is on the way and all will be better than new.

New ECU issues

Just picked up my 2016 with the new ABS ECU and it's not very good. Real twitchy when the throttle is open slightly which is where lots of the riding is done except when you on it. The non ABS ECU was beautiful. Silky smooth with no throttle issues, but no speedo and F1 and check engine light were on. Now the bike bucks and surges and is not smooth around corners. The dealer is checking to see if they sent him the correct item. Looks like I'll need to spend the dough for a remap. BTW: I don't know what to think of the severe slow down when the throttle is backed off. I find it makes it a bit more difficult to ride because your on and off the throttle alot and that's right in the snatchy area.

I do love it, handles great and a great motor, but got to get rid of that bucking surging throttle. I suppose when the dealer tells me he's gone as far as he can go I'll spring for the remap. As I said previously the other, non ABS ECU, was smooth as silk. You could just roll into the corners with no twitch, just smooth power to the ground. I'm spoiled after riding the bike with a smooth throttle response.
