I have received advice from you guys who are definitely "in the know" that for my SuperCharger build I should be going with the PCV.
That said, and advice taken...but DynoJet is not giving my Dyno guy (Dan) the feedback he requires and there is slow to little response from their customer service for a SuperCharger application. And now they don't even offer the PCV on their website ever since coming out with the PC6. Dan tells me that the PC6 is a dumbed down PCV and that it won't give me the results I'm looking for. I keep telling him what you guys have told me...that I NEED the ion/knock sensing function of the Delphi unit and that the "piggyback" PCV is the only way to retain this function.
Dan is really pushing the DTT. He is extremely experienced with DTT. He has built Bonneville land-speed bikes using DTT. But he hasn't ever used it on a SuperCharged V-Rod. The owner (Nick) of the Holy-Moto equipped V-Rod that Dan was supposed to have tuned prior to mine has decided to tune it himself with the DTT Autotune because Dan didn't have appointment availability prior to the start of the season here.
So...what should I do? My appointment with Dan isn't until December and in fact I haven't even started my tear-down as I am still waiting on the last two parts I need (a back-ordered pair of 8027K bearings coming from Manchester H-D in England). I am loathe to tear apart a perfectly good stock 2003 without first having all the parts I need to put it back together.
Should I proceed with finding a PCV from an aftermarket seller and try to tune it myself with Autotune since Dan seems unwilling to budge on the DTT issue? Is there another Dyno guy in the NorthEast anyone can recommend who has experience with SuperCharged V-Rods and the PCV?
Not sure what kind of support you're (or your tuner) is looking for from dj. I have had good success in my dealings with them. No, they aren't the fastest, but they have always answered me.
I am running the TTS sc unit, and I have a boost limiter currently set at 6psi. I run the PCV with AT module. Zero complaints. The unit works VERY well. Initially the problem was the idiot running the software, but the unit did as directed. The learning curve took roughly a season, but all good now. I would HIGHLY recommend it for boosted applications.
I started a few years ago by installing S2 cams, and purchasing a TTS tuner. Took it to a local dyno guru, who charged me 360 to tune it. (At the time I knew very little about tuning, therefore trusted him) When I got the bike back, there was a HUGE flat spot, roughly 3250 to maybe 4500 rpm. Spitting, sputtering, coughing.... just plain crap. (Beginning of learning curve) took it back. Guy said "thats a characistic of the cams, there is nothing can be done". I KNEW that was bullshit, but he wouldn't DO anything, OR give a refund..... So, I found my way here. Begged for someone to help, or give me a copy of their tune (thats not how it works, but I didnt know that then) that works. Eventually, Ron agreed to help tune it. Over the course of that summer, and 100's of tuning runs & cals, we (Ron) got it right. No flat nothin. Ran excellent!!!!!!
So, I decided to go with a sc. Using my past experience as a guide, I was keenly aware that a dyno tune just was NOT gonna be an option. (No skilled tuner anywhere near me, and I dont own my own dyno) so, how???? Looking into it, yes,I looked into the scaling, and in the end I would of had to utilize my TTS tuner along with scaling unit. This method however would require the use of a dyno. (And looking back, it wouldn't of been a one & done deal, as this isn't how it works either) so, wanting to retain the spark knock feature (I've utilized this, looking back in logs & seeing a knock event & therefore can tune it out if needed) and the stock ECM (as I see it, the most reliable unit out there).
So, the only real options left was the PCV or DTT. The DTT also requires the use of a dyno. (Also not a once & done, as this is NOT how it works) so, PCV & Autotune it was. That is the only thing out there that allows street tuning.
So, added wide band O2's to my exhaust & installed the PCV. I then tuned the stock ECM, using the TTS unit, to the bike with the now Jones SCS2 cams. At this time I tuned it with sc NOT installed. Got it running really well in NA configuration. Then I added the sc & tuned using the PCV to handle the boost. Again, the limiting factor here was the idiot running the puter. But, eventually it was figured out ( thanks again Ron) and now the bike runs. Runs VERY VERY well. VERY happy with the result.
I've learned a TON!!!!! And now, looking back, I realize I didn't know what I didnt know. Quite naive 😕...... I can tell by your writing you are me. A few years ago. You know not what you are asking...... but thats ok. It is a LONG and (to me) quite interesting road.
So, thats the jist of my story. Ask whatever you like. And I will tell what I think I know, but don't get pissed if it takes a minute to respond.....
