And that was pretty straightforward.

You unplug one, you plug the other in.



And, incase anyone wants it - this is the file it was preloaded with:

HERE

I gave SCS/Delta the info that I had a 2015 with short loud pipes, decat, and no IAC and thats what they loaded for me.

Yep, plug and play....have yet to seriously delve into mine...will do though!

They advise to disconnect the battery before plugging or unplugging the ECU. Let us know what you think of the Norton 961 race cans map the loaded for you . I think you will be happy with the extra kick 4000 revs and up.

@TonyA Have just had my first ride, the weather is pretty ordinary here - and I saw a break in the clouds.

Mixed thoughts to be honest. Over 4k and out to redline - no doubt it's significantly improved.

Around 3200 / 3600? not so great. Not bad, just feels flat. Like its being retarded. Improved as it warmed up. Then hits 4k and really takes off. I'd like to copy and paste the 2500 to 4000 from the other ECU to this.

One thing I will add. I did follow the documented procedure for configuring the TPS before I rode the bike. For clarity - this one:

This was due to the fact that I noted that throttle wasn't at 100% in the SXTune display when wide open on the bike. I'm not yet discounting I have introduced an error - but it seems unlikely.
 
Yes , That is the procedure I used to configure the TPS. Yes , I had the same flat spot. and the same basic observations . I have emailed Matt Payne of SCS UK about this , and have sent him the Typhoon map and the D400 Race cans map to look at. I will report back asap. I have just recently (last fall) installed a Dyno Jet PCV and had it dyno tuned. This helped tremendously , but I would still like to get to the bottom of the original cause.

Sorry @TonyA - I might be confused on this. You have a D400 and a Dynojet as well?

Yes both. D400 and DJ PCV . The dyno tuners around here use the PCV a lot and I could get support. I am sure in the right hands , the D400 could be tuned on its own , without the need for the DJ-PCV . The use of SX Tune and SCS Delta 400 produced too many huh , what never heard or worked with it answers. So , At this moment I went with the flow and got it tuned with the PCV piggy backed to my D400 and Race Cans map. The reason I started this Delta 400 thread was so that people like you , me and other D400 users could compare notes. There are some of us out there , but not getting much feedback until now. I don't want to scare off 961 owners from getting a D400 upgrade , but its not quite plug/play set and forget yet. It can and will I think get there someday. So if you had to ask me am I going back to the Typhoon ? That would be NO . The only reason I would go back to the Typhoon is if I was down or troubleshooting . The Delta 400 is a better , current , fully supported ECU , and the way forward in my opinion.

@TonyA completely agree, it's a significant improvement in many ways, and opens the door on a lot more as well.

I'm not particularly scared of EFI. I believe a few good maps shared from people with noted setups will make all the difference.
 
So, SCS have replied to an email I sent them already and provided an alternative map for me to try - very fast response amd interesting information.

Hi Jason,

There was a revised spark map for the original SC ECU to address a detonation concern in that rpm range. It also coincided with the switch from Active Technologies to Jenvey throttle bodies. The calibration release changed from PR3 to PR4.

It seems that your old SC ECU has the PR3 map, which is why it feels stronger between 3000-3500rpm.

The Delta 400S is fully programmable, so you can take it to a dyno and tune it however you wish. But it could be worth trying the spark advance map attached, and see how that feels.

Thanks
Simon

Subject: Delta 400s ECU issue

HI,

I own a Norton 961 and just purchased a Delta 400s from you which arrived on the weekend.

As some detail I have a 2015 bike, decat, with the short loud pipes on it and the IAC removed.

The bike was already fitted with an SCS ECU from factory, #9177792.

When I received the ECU it was preloaded with a map to suit - which was really great.

i swapped the ECU, and managed to get the bike started with no issue. I then reviewed the sensors and noticed that the TPS wasn't getting full range in ECU despite being fully open on the bike. Based on that I followed the "configuring the TPS" section of the manual which resolved this.

When I took it for a test run, I noticed that within the 3200 to 3600 rev range the bike was really hesitant, and felt very reluctant to do anything. Then once it hits 4K it really takes off strongly to redline.

Given that the original ECU had a tune that (I understand was from your company) is there anything you could suggest to improve this? Maybe I'm being optimistic but ideally I'd like the 2500 to 4000 rpm performance from the standard ecu with the top end from the D400s. I will say the top end has drastically improved with the new ecu, quite surprisingly so.

Is there any way to compare the two, or could you offer any suggestions or alternatives?

Thanks in advance,

Jason



So, from some reading, I believe Active Technologies went into administration in 2011/12. The company was bought out by two employees, and is now AT Power: https://www.atpower.com/ and https://www.facebook.com/ATPowerthrottles/ and https://www.instagram.com/atpowerthrottles/

Interestingly - at some point I think they were from Norfolk (as are SCS)? Dunno if there is an overlap.

Using the compare function in the SXTune software, I compared the first map they sent me to the second. The only differences shown are in the timing - nothing in the fueling - but it's substantially different, in some cases by as much as 15 degrees.

I need some dry weather and a day off work so I can test it.

Nice work , Thanks for the feed back . I am right behind you , I will be loading mine soon.

Wow Gojuu , I see what your saying about the changes. Lots of RED ! And some spark advance values were negative in the previous file.
I am in the middle of freezing cold winter here , So you will be ready to try it out before I can. By the way , when I did the IAC block off I ended up with TPS volts values of 1.06V Zero % throttle and 4.79/4.80V @ 100% . This might give others a starting point and get them close.

I uploaded the map earlier, and managed to get out for a ride.

Change is as big as I'd expect from seeing the differences in the two maps. I was looking for an improvement between 3 and 4k, and got it into the 2's. I can comfortably use that part of the rev range and there is no hesitation at all.

File is HERE for anyone that wants it.

Sweet ! Now you have a very satisfying power band !

@TonyA it’s a fair bit broader than I expected actually, well worth the ECU change.

It’s worth noting too - that I didn’t have to change the sensor config values that I used for the TPS / config - they remained constant after the flash.

I think my next plan is to remount an ODB port somewhere that’s accessible.

I have K&N clamp on air filters replacing the Air Box . Without being able to tune the SCS D400 to suit this , I used the Dyno Jet PCV on the Dyno. I will attach a picture later , I think it looks nice.
 
@TonyA having already adjusted fueling with the Dyno Jet - I think you're going to get a surprise when you see the difference this timing makes.
