Did you drive cross country for this tune?

No just rented out a dyno and schedule a remote tune.Did you drive cross country for this tune?
was just wondering how u managed to put 1500 miles in a day and few hours.No just rented out a dyno and schedule a remote tune.
What were your fuel trims looking like?**UPDATE**
Vehicle: 2017 Civic Si Coupe
Total tuned time: 14 months
Total tuned mileage: 10,000+
Tuning device(s) used: KTuner v1.2
Tunes used: TSP Stage 1 Map 3, Recently upgraded to TSP Stage1+, running Map 3.
Fuel used: 93 Top Tier
Additional engine mods: K&N SRI
Problems/issues: Recently had some high fuel trims. I just dumped a bottle of seafoam injector cleaner and the trims immediately stabilized. May have to replace injectors soon. No clutch issues so far from upgrading to TSP stage 1+.
Driving style: Fairly Aggressive but no WOT under 3.5k rmp to preserve stock clutch for as long as possible.
Tuning experience notes: Zero tuning experience prior to this but it has certainly given me the bug.
*UPDATE*The CVT can easily handle 200 lb/ft...
Keep in mind that 250nm number used on the Hondata CVT tq table is more torque than you think. Hondata is supposedly using their own ecu torque calculation. It's not the straightforward math you'd assume.
We had this discussion years ago at the forum and Hondata wasn't very open to discussing the calculation formula used or the actual numbers in lb/ft.
Btw, when you raised the torque limit, I hope you only increased it above 4000 rpm for safety reasons.
The basic keys to CVT safety are keeping torque subdued a bit below 3500-4000 rpm and NEVER brake launching.
There actually was a big thread where Hondata destroyed a CVT and "found the CVT's power limit" Unfortunately, they never said what those power limit numbers were.
Hmm.. interesting. I’ve tried reuploading but I’m still getting the same problem. Even when i tried loading the +6 basemap as well It won’t build up more than 3 bars of boost. I’ll probably try again tomorrow but I don’t want to keep flashing and refalshing back to stock over and over again because I did it for a total of 4 to 6 times yesterday.Sometimes, for whatever reason, a tune doesn't "take" so you just re-upload. Honda didnt add some sort of tune preventing device or chip.
As far as the CVT, when I first put my car in D in the morning there is a light delay before it goes "into gear". That's fairly common.
small updateVehicle: 2019 hatch sport
Total tuned time: 4.5 months, tuned 2 weeks into ownership
Total tuned mileage: 6000mi since 1000mi
Tuning device(s) used: ktuner
Tunes used: Mostly 18psi starter map, had 21psi for the past month but reverted back to 18psi a few days ago. Clutch already takes a beating in LA + my driving. And the 21psi peak tq seems to be right at the limit of stock clutch based on what I read here (~260wtq). Of course I'm never wot at 3k but still. I like to beat on the car a bit without sweating
Fuel used: 91, initially shell but switched to chevron because when people have contamination issues it's usually shell lol
Additional engine mods: Prl cai (race maf), prl intercooler, 27won catted dp/fp, straight through magnaflow muffler
Problems/issues: The prl cai was running lean even with the provided maf scaling, so I had to adjust it a bit with the help of @PowerPerLiter. LTFT is between 0 and -3 now
Driving style: When the engines cold I try to avoid boost and heavy throttle. When engines nice and warm I like to blast through 1st and 2nd between lights, kind of sad but 2nd is my "fun gear" due to the traffic/laws and street layouts. On the freeways I'm usually just reacting to random slowdowns and creeping along unless it's late at night. For context I'm currently at 24 lifetime mpg, rarely do I actually get to cruise. Also I swear the mpg went down after I switched from stock maf to race maf, used to be a solid 28mpg. Or maybe I've just been in more stop and go the past month.
What were your fuel trims looking like?
Negative number would be running rich with too much fuel. I'm surprised the seafoam did anythingLTFT was sitting at about -20 and seemed to be getting worse. Fuel trims stabilized very quickly after dumping the seafoam in. Averaging around -5 or so now on my LTFT.
