As Andy said they all have to be reprogrammed to the specific PGM.
The good news however is that if you want the 030 program you don't actually need a 030 card, a 000, 010, 020 or 030 will accept a 030 program. I actually think a standard card will take a 030 program but I am not 100% sure on that one.
According to the tyga wire splice instructions "most" of the stock electrical systems still function. What systems don't still function? Also, after doing the wire splice do all of the stock electrical systems still work with a standard card if one wanted to use it occasionally instead of the HRC card or are you limited to strictly using the HRC card from then on? Thank you in advance for any and all information.
The following features no longer work once you do the wire splice and install the stock card. Mainly because the wire splice has bypassed them. You would only regain their functionality if undo the splices.
1. 2T oil tank low level warning
2. Side stand down warning light
3. 2T oil pump solenoid
4. Something else I probably forgot.
Will the bike run, yes. But remember, when you use an HRC card you need to re jet so its not going to run correct.
There is lots on this topic in the forum if you search around.
Eric posted a method some time ago where you can perform a reversible version of the MC28 wiresplice, that doesn't involve cutting/soldering the harness...
I seem to recall someone also wiring in a relay to a switch, to do something similar, but I think it was on our old nsr250.com forum, some 25 years ago, and is long lost information unfortunately.
A spliced MC28 will run with a standard card, but it runs like crap in my personal opinion... and experience! The jetting requirements for either card differ too much to warrant even bothering to try. It's all or nothing. Anything else is a waste of time, I say. It was great marketing at the time, and hyped as simply exchanging cards, but we all know the reality as it turned out.
Honestly, I've never seen anyone really that bothered about using a stock card. Once you've liberated 60-odd horsepower with the HRC setup, you'll never want to go back! It's just very unfortunate about the cost and inconvenience with the MC28. _________________ Andy.

So does the fact that the 2T oil pump solenoid doesn't work after doing the splice mean that you have to premix?
You don't have to use pre-mix, but you should ensure the pump is accurately set. There is a possibility of fouling the plugs at lower engine speeds without the solenoid control, so ensure you only use the highest quality, low-ash/clean burning fully synthetic 2T oil, and that the jetting optimally set. (Please do not ask for/discuss jetting settings in the public forums. HRC base settings are available in the Tuning section of the main site.)
You won't be able expect to just jump on it and ride it like a standard road bike, however there is no reason not to still use the pump if you want to. We've set up plenty of dual purpose street/track bikes with oil pumps, and never had a problem. The downside on a track bike is the weight and possible failure of the pump (I've personally never seen an NSR pump fail in 30 years), and the effect 2T injection can have on overall fuelling. Pre-mix is far more controllable.
We've long recommended and used Rock Oil Synthesis 2 Injector*†. If this isn't available in your region, then look for a 2T that meets the same specifications.
*We use Rock Oil Synthesis 2 Racing in the NSR500Vs. "Racing" is not suitable for injection.
†We are not sponsored or financially involved with Rock Oil in any capacity. Other oils are available. _________________ Andy.
