those running TSP tune need your help!

[tehSteve]

I'm posting here because I can't figure this out. I ran a CDV delete and PRL SS line for a long time. I had no problem shifting from 1st into 2nd even at 4k rpm. Usually that required being an extra second slower with the clutch.

Fast forward to the TSP Stage1 Tune. It runs excellent, but no matter if I am in regular or sport, my 1st to 2nd shift is extremely terrible. To the point of the rear end of the car "bucking". Even shifting from 1-2 at 3500rpm it's as if I am popping out the clutch on the shift, but I am not.

Does anyone have any pointers? Is the 1-2 shift still supposed to be slow? I've tried tuning off the AC, readjusting to a variety of seating positions, shifting faster, and shifting slower. Still nothing. The only time it seems to cooperate is if I don't hit boost. But that is hard to do if you live in a place with a lot of dangerous intersections and you really gotta get going from first.

I'm suspecting that I need an upgraded rear motor-mount due to the quick spool, boost hitting harder, and perhaps getting back on the throttle a little too hard. I'm not sure.

What is the trick going from 1st to 2nd on this TSP tune?

It sounds like you're not quite used to the rev hang disable paired with the standard throttle padding. This does require a little relearning if you're coming from a calibration with all the soft options.

The combination in the calibration is meant to provide the most direct feedback to the driver from throttle movements. Honda has done a great job of softening and delaying all of these movements (effectively numbing it), but from a performance standpoint, it introduces unpredictability (throttle staying open or closed when the driver is commanding the opposite for a moment). If you've driven the car for a while, you've already trained yourself to drive with that behavior.

Give it a week of daily driving. If you can't get the hang of it by then, shoot me an email, and I'm happy to work with you.

Thanks! This might be just me pressing the gas pedal too hard resulting in the motion after my 1-2.
I think investing in a rear motor mount might help what I think the engine is hopping

I noticed a slight difference when disabling rev hang with the Ktuner 19.5/23 tune. It definitely requires slightly extra care for a smooth shift. But like anything, nice your muscles learn, you won’t even notice. If able, drive another car with a tougher clutch. It will show you how easy the Si clutch is, even with the rev hang delete.

I already have Stage4 twin disk on my EvoX
Now to figure out if it is a clutching issue or pressing the throttle issue.

Ive been kicking around the idea of an aftermarket motor mount. I don’t launch my car much, but I’m curious as to the benefit. My next focus is a Type R shifter with Acuity upgrades, and possibly a PRL clutch line. But I don’t have any issue launching the car with the stock clutch/shifter setup. I find it really easy to just stab the clutch for quick shifting cuz it’s so light.

Been running TSP stage 1 for days. Before that, I’d been running starter maps with rev hang on. With this tune, it just feels like days of old. Not much adjustment for me, first Honda was an ‘89 CRX Si. Loved that car.

Hahahaha! Yes! It's all coming back to me now!

I can now confidently say that the TSP Stage 1 is no different than any KTuner basemap in terms of 1st to 2nd smoothness, as long as you've been running the rev hang delete with standard padding. Exactly the same.

Everyone is a newb at some point. Didn’t want to change too many things on first flash so I could pinpoint an issue with a setting if I had one.

I never ran the base maps I must have a lead foot when pressing the gas in 2nd, although it never chirps, but I do raise the RPMS to 3.5k-4k during shift time
Still gonna get that motormount

It's ok! Just giving you a hard time and dusting off Jim Varney in the process. My gen 9 had rev hang bad so it was probably the very first thing I checked off when I got Ktuner on the genX.
