    Well I'm almost certain that the startup issue is in the tune. Think I'm gonna get HPT soon. Been tinkering again lately. Tinted the headlights and did a quick detail. Hope to get the windows tinted real soon.

    So when cold it starts and idles fine. But when I start it up again when it's still warm it needs some coaxing with the gas for about 30 seconds. I have a feeling it's in the tune...
    Went ahead and ordered HPT. It was indeed in the tune. Man, my first tune was a mess, lol. I'm certainly not a pro now, but HPT graphs let me see exactly how choppy it was. VE and MAF tables looked like chit. I wish I had started with this tuner, honestly. Yet I still find myself looking in the same boxes for the hundredth time, at least once a month, for my dhp tuner. Rip...

    Working on tuning the MAF a little more. My wb/AFR error is around 1.2-1.5. At wot high rpm it gets a little worse. Running 19° with just a tiny bit of knock sometimes between gears. I'm encouraged enough that I think I'll try the smaller pulley (3"?) again.

    What's the safest, highest rpm y'all run on stock heads?

    dont waste your time on the ve table, just maf tune it.

    set your pe afr to like 11.6, then work on getting the wb to read the same via the maf. 10's it will flood and dog, 12 will be lean and cause kr and slowness. mid 11's is the sweet spot.

    i was up to 21 wot on the gen 3 blower, i broke it tuning the gen 5 n*, now that i got it fixed up again i need to add that timing back.

    Yeah I'm just doing MAF tune. I tried a ve tune first, but it was such a mess I had no idea how to really dial it in. I went back to stock ve and MAF table, and car instantly ran so much better. At WOT I'm commanding 11 and getting 10.34. I have base AFR for PE at 11.7. Just need to figure out what other tables are also subtracting AFR. Is this from AE maybe?

    Dunno why I can't edit my post. Anyways, Scott did you zero out your adder tables in PE section? I can see the commanded dropping in a long wot pull. So that's definitely where some AFR comes from, maybe all of it. Or maybe it's safer to just set my AFR to 12.2 instead of 11.7 and let the adder vs rpm vs time do it's thing. That is if I can start the pull at around 11.9 without knock.

    you got pe pedal enable, then the time vs rpm is zero'ed out. then pe afr file.

    scan your commanded afr as well as the wb you should see commanded drop to what you set it to when you enter pe mode, via your tps reading. then adjust the maf to match your commanded. zeroing out that time vs rpm table kinda makes you maf tune it some, it will lean out on ya when in the gas a long time, like a 1/4 mile pass.

    i pretty much hit the arrow keys to frame by frame the scan, watching maf hrtz and the wb, if i start to lean out on the wb i add to the maf from those cells up. easy way to add is to highlight the cells then type a 5 in the text box, then hit +. will add 5 to those cells. iirc im reading the file in grams/sec id have to look to be sure. ive ended up adding 5 a few times to the file to get to my target afr.

    you need to lean it out some. and change a few settings in commanded af while in pe.

    get your o2 reading in MV iirc on that scan too. get injector duty to work also.

    you'll also want to re set up the timing graph. mine looks like this, same for the retard graph. you copy the row and columns of the timing file in the editor to the scanner set up.

    Yeah I screwed them up somehow. They worked fine until I swapped the row and column to match my tables. Not too worried about it right now. I want to dial in the MAF first.

    Made a couple changes based on your tune today. Sadly all the local e85 stations have shut down their pumps, wtf. I got enough info for a new flash, but I'll have to see what's happening with the fuel because I'm on E.

    Thank you sir! Funny, I just got done reading through your truck build log. I'm jealous of the knowledge you have on those older engines. My dad never taught me a damn thing. But be sure I'm teaching my 10 year old as much as I can as I tune and repair. I love the history of your truck.

    Scotty or anyone, any idea how to minimize the wonky readings when decelerating? When tuning MAF it gets kinda messy on the low end because of the fuel being dumped. I'm guessing it's in :Fuel>Transient but the settings are hard to wrap my head around. I'll keep digging but if anyone has a cheat sheet that would be amazing. I notice in the logs, on decel, that inj pulse width goes down to 1.7ms and holds for a couple seconds, then drops to 0 and my afr leans up good.

    Scotty, i noticed your settings are changed. Maybe you can help me understand the changes? I'm tempted to just copy yours, perhaps it will solve the issue, but I want to understand the changes first. My car is running better than ever i just don't want to ignorantly make changes.
    nti
    E85 is still unavailable around me. No idea what's going on. So tuning is on hold until they top off the pumps

    id take your file and copy it, then copy almost all of my tune over to the new copy you made. flash it, see how it acts. cant hurt to see if it makes things more normal.

    im not sure what files your referring to really....

    you should really make two tunes, one for gas, one for corn, as this corn shortage could happen at the worst time again. nice to just take a minutes and flash a gas tune in and fill it up.

    I'm thinking it's in my injector tables. May be at the lowest minimum pulse width I can achieve with these injectors. Or some other setting. I remember using tiny tuners when I had dhp to adjust settings that aren't available to me now. I'll just have to make due with what I have. Exact data for the SD 60lb injectors is non existent. I will try your settings eventually.

    Dunno if I could get a decent 93 tune with my 3.25 pulley though, without pulling more timing. Would like to have that flexibility though! Main reason I went e85 was for more safety margin since itsy first car I've tuned. Hence why it was so pig rich, lol.

    Oh, on that note I learned something. Didn't realize that you could get knock by being too rich. When I first started redoing this tune I messed up my injector flow rate. It would drop below 10:1 AFR and would sky rocket my knock reduction. Interesting.

    Yeah Siemens Deka 60's. Trying to find specs on these is impossible. What I ended up doing was taking the stock IFR table and scaling it up to 60. For the longest time I had 61.7 across the table. This was done by someone else. Scaling them proportionally to the stockers helped a ton. Close enough will have to do. Still haven't figured out why my duty cycle isn't scanning. But I think I was around 70% last I remember. Kinda sucks just making a best guess on injectors. Every tuning guide insists that injectors are set up right before tuning. But considering I've ran 4 years on basically guess work, I think I'll be ok.

    BTW, what meth kit are you running. If I take this further I'm thinking meth or rockers. Been checking the yards for a gen V blower. There are 4 or 5 gen III's there. If I find one that might be good enough for awhile.

    i have a aem kit with progressive controller. runs about $425 iirc i got mine for 360 ish off amazon. weeks later the price went up lol


    i got my gen 5 off lkq. paid 117 shipped for it, came off a 07 with 105,000 on it. the coupler was even still good lol but the vac tree up top and bbv and evap sensor were all smashed, i think the bbv was broken by the last owner as it had rtv or some crap on it trying to fix the broken nipple....i took all that stuff off my gen 3, fit right up perfectly.
