Default S&S IST Ignition

Just started looking into this and it sounds kickass albeit expensive.
Could anyone shed some more light on this? Why aren't more people running this? Price?
With all the money we stick into our bikes it would seem having instant timing adjustments on the fly would be worth it to more than just sportsterpaul.

Is this a one size fits all? Part # for a carbed 05 if not.

I know a lot of you are running the tc88a. I've got a SERT for the stock ignition.
I dont like the idea of being limited to 45° with the tc88a or not having a seperate map for each cylinder. But if/when my stock module crapped out I was going to get one anyway.
Bad thing with the SERT is it's married to one and only one.

This IST sounds too good to be true.

The IST is a nanny for an engine. The high performance bike get limited with this ignition. I've saw they program the IST to not listen to the Mikuni noise, but still has problem with other clapping. The anti-knock sensor is what give problem with high performance engine. With a normal engine, CV carb, no problem.

Fair enough. So define high performance vs. normal.
Also, it's my understanding there's optional programming software sportsterpaul doesn't even use.
Could it not theoretically be programmed to ignore certain "clapping" from the knock sensor?

Scratch that programming bit. Seems it was the guardian software.

The knock sensor has to be defeated at S&S
Why would you need more than 45 ° timing ?

Why is there a significant amount of 50° timing in the higher rpms backing off on the stock maps of the SERT cd? And a timing difference by as much as 3° or 4° between the front and rear cylinders before, during, and after max is reached? A difference in both directions briefly. And how important is that? I do t know. Maybe you do.

For the record there are several others on site that run/or have run the IST ignition. Mine, on the ‘06”R” has done over 100,000 without missing a beat. Was in touch with S&S trying to get another unit for the ?Hot ?Rod bike,(an 89” stroker), and they were no longer available. My ‘06 has consistently returned 55-65 m.p.g., Run from sea level up to 10,000 foot elevation, solo and/or two up and loaded with nary a whimper but most importantly when I’ve gotten bad gas or with higher octane not availible the only way I knew was the mileage dropped noticeably, but it still ran good. My reason for running it was just plain old peace of mind, that and the fact that it was always close to ideal tune regardless of physical or environmental conditions. Hell, I can change cams, compression, exhaust and it just keeps working. I concede that for that last tenth or two of h.p. youcan do better, Scott,”Grind”, proved that some time back. Me, I’m just happy.
Oh, if you find any let me know, thanks.

Yeah, I read that old thread from 2012. Seems he quite happy with it tho.
I think I would've been too. I've never been out to squeeze ever last pony out of it.
Might as well just keep the stock ICM with the SERT til it craps out making the SERT useless unless I buy another one. Got this one dirt cheap on ebay. I don't see any benefit of going with the tc88a until then. Except no help with mapping since no one else has one of these either.
I was able to figure it out tho and there's the maps on the CD. Just have to do some tweaking with the new cams and exhaust.

Most of the big inches S&S engine came with the IST, warranty call for it. For bike that run 6250 rpm max, the IST is a perfect set-up. Rev limiter is even set lower for the first 500 miles in the brain of the S&S ignition. Lot of HP junkies get their big number flirting the 7200 rpm.

I set mine at 6500 with the SERT and only bounced off it once or twice. Max is 7000 if I recall.The IST will do 7200 too. Except on a warranteed S&S motor. Need the software to do it tho. If you don't buy the software it stays at the preset 6250.
Oh well, it's gone for good anyway. No biggie. I'll do the tc88a sooner or later unless my stocker hangs in there for eternity.
