TD Max Pump 17 Issues

That's a sweet deal

Awsome service from TD! So hard to find that anymore!

Let me tell you how I solved my ecu problems.....after the dealer replaced the ecu I took a “BLACK MAGIC”marker and blacked out that crazy looking ray-o-vac CAT on the side.....never had another problem!

I forgot to Mention there is a factory boost gauge.
It's in inches of mercury but you can convert it to psi
Could get in handy to troubleshoot a boost leak...

Go in diagnostic mode...
Both buttons left right press and hold.
Then go to diag and map sensor.

Also find the boost leak... the more I think of it the motor I believe there is a boost leak because as I said max 17 does not have the boost leak code enabled. If you don't reach target boost it will run very badly super rich and not make power. The fireball and misfire leads me to believe you are at 9:1 or low 10 air fuel ratio due to severe underboosting.

Question: Doesn't the ECU see the amount of boost and use that as one of the inputs for the fuel curve?

Thanks for the details. The fuel looks good according your report.

OK now I remember who you are... after you there were 2 more écus that couldn't flash from the diagnostic port. But they could also be flashed through the direct port.

We decided to investigate further and gap did some testing on their diagnostic port flashing system. We found out that one could only be flashed at room temp and the other had to warmed up to be flash able. That is for sure a rare anomaly in the ecu.

We have yet to see one that doesn't flash at all. We didn't know about this solution back when we tested your Ecu you were the first.

I really want to help and correct this issue. Now that flash I'm sur is fine as you know.

There are 3 solutions:
Easiest solution is trying to figure out the problem. Swap new plugs and gap to. 020 because you now fouled the plugs.
Also find the boost leak... the more I think of it the motor I believe there is a boost leak because as I said max 17 does not have the boost leak code enabled. If you don't reach target boost it will run very badly super rich and not make power. The fireball and misfire leads me to believe you are at 9:1 or low 10 air fuel ratio due to severe underboosting.

2nd solution is the coolest but you will lose ecu for a few days. We will give you the highest priority and ship ecu back express.


We will perform the special procedure to flash it with your own flasher which we will sell you at 40% off regular price for your troubles. And we will flash it using your flasher and put in the jukebox flash which as all the flashes switchable on the fly. That way you won't need to reflash the sled at all. In the event that you want to reflash we will show you the procedure of heating that ecu to x degrees to flash it. Having the flasher will allow you to diagnose the problem as you see all your live values and can datalog and send me the log.

The last solution choice is just borrowing a flasher from us and just using it for diagnostic purpose. You could also do the ecu heating solution to flash your odd ecu that worked with the few other we found like yours.

If you decide to keep the flasher we will give a super deal on it.

Ben, thanks for stepping in to help out. I will take option three, however please pm me total price on option 2...as I might be swayed. Does option 2 require the purchase of an ipad which must stay on there all the time??

Pulled plugs...will replace anyway, but don' look fouled.

Are you running a 3 bar map sensor?

Speed/density tune at least that’s what my viper is, don’t think winders have a mass air flow sensor?

No.. You could use phone just for diagnostic and keep in pocket or get one of the phone mounts magnetic charger it's cheaper..

It does it uses a mix or throttle positon vs rpm and boost compensation map. If the sled underboost it will run richer. With a map sensor upgrade we use more and more the boost sensor as a major fuel adjuster over 15psi.

I believe I'm being haunted by a gremlin and would be interested in hearing input in developing a path forward in hopefully finding a cure. First a little history:

2017 Yamaha Sidewinder RTX SE with 2200 miles, bought brand new last winter, put TD Eco Trail Flash with a SQ muffler. For clutching I ran Dalton QAY-70 weights loaded with the 1 inch allen (4.1 grams) for a total of 74.1 grams. Springs/helix everything else stock except for updated torlon rollers in rear secondary. Sled would spin 9000-9100, once in a while if hot running is soft snow might drop to 8900. Sled ran flawless all winter and was a blast.

This year I loaded TD Max Pump 17 and also a CAI and OSP Racing muffler which is basically the same as a TD Turboforce. Per Ben's instructions I loaded Qay-70s to the hilt at 77.4. Would only spin 8300, so dropped weights a gram to 76.3, would spin 8400, dropped weights another gram to 75.4 and added stiffer secondary spring (TPI orange) and would spin 8700. Bear in mind, I know this thing isn't right so I'm holding it 4-5 seconds and letting go as it doesn't feel right. In my head I'm thinking the sled feels no different than last year and my butt dyno is telling that this thing isn't making the claimed 285 hp as it should.

So this morning I figured I'd go back to basics and eliminate some variables. I set sled up just like I had it last winter, SQ muffler, stock airbox, Dalton weights loaded to 74.1 grams, stock springs and stock helix. Took sled out for some testing and assumed this thing should be banging off the rev limiter!! To my dismay, would only pull 8700 rpm. It's turning 3-400 rpm less than last years Eco trail????? WTF??? I'm making less power???

So......I'm thinking I must have a boost leak. I removed all the panels, checked......double checked... and then triple checked all the hoses, clamps, air box, intercooler, and can't seem to find anything out of the ordinary. I was thinking perhaps the BOV crapped out so I removed it, checked the plunger and all looks legit. I pushed on the spring valve and it needed a very healthy push with my thumb to get it to open.....so I'm thinking this looks to be sufficient also.

I could take it to the dealer, but he'll blame it on the tune. Does anyone have any ideas on where I should go next?

Btw what belt last year and this year?

I'm not running 3 bar map sensor and have been using 8jp factory belts.

Right now at a crossroads as I'm waiting for the flasher that Ben so graciously sent me to assist with diagnostics.....thanks Ben!!

Also waiting for Beermans boost leak tester which SideHogger mailed out today....thanks Beerman/Sidehogger!!

In the interim, I've installed a new set of plugs gapped at .20, pulled clutches apart, cleaned and checked everything and everything appears up to snuff.

Checked all hoses, vacuum lines, turbo bolts, wastegate, and again couldnt find anything out of the ordinary. My impatience got the best of me and I fabricated a 5 minute boost tester. Although crude and ad hoc in design, it would at least allow me to find a blatant leak if one exists. (Ex. Hole in intercooler and/or busted hose i couldnt see with naked eye.) At any rate, my tester would take air until the duck tape would blow. Although I did not have a gauge, I could see all the hoses swell as I added air until the duck tape would fail. I would estimate possibly 15-20 pounds before failure and unfortunately no leak detected, albeit testing conducted with an inferior design!!! Lol. So.....if a leak exists it is going to be a small one imo.

At this point, everything is on pause until I get some diagnostic tools. Thank you everyone for your assistance and special thanks to Tom, Beerman and Ben at TD!

Up now in the Western u.p..... Again... Max spool 17 rips... Two Doo buds of mine rode... Both are looking at a SW with the TD tunes...

Yeah, a leak doesn't seem likely given your test and description. This one is weird. I rode last weekend in warm temps with just PT/CAI and it was ripping. I haven't tried 17Max yet, but will be soon.

Seeing any knock counts? What fuel are you running?
