my RA is at the 2000km mark and the shifts in manual mode are pretty much instantaneous, even when revved to like 4-5000rpm

 

Mine on upshifts, it will shift immediately. On down shifts, it takes a little longer because it needs to first match the revvs.

 

my thoughts on that exactly...but hey we have the best of both worlds....a slight delay will not ruin my driving experience. I just wanted to be sure if this issue was just with me or if it was common amongst all RA owners.

 

Perhaps the delayed upshifts in normal mode is just the transmission allowing the engine revs to drop in order to rev match?

 

I have also noticed the delay to be long near redline, otherwise (2000-5500RPM) it is right away.

 

I too have noticed the delay. I have banged it off the limiter twice. I pull the up shift at 6500 and twice it has not shifted until it sings past 7000 and bangs the limiter.

This is at WOT in 1st with it in manual sport mode.

Not fun.

I even had it not shift once when I was rolling around 10 mph in 1st Auto sport mode. I hammered the gas from the roll, and it never shifted. Just banged off the limiter. Did it 3 times and it never shifted into 2nd.

I had to stop the car, put it in park and then everything was fine. No codes came up.

And believe me, I did check to make sure that the car was in auto mode. The display showed "D1" "Sport".

 

It makes me wonder when I started this thread how many people would respond with the same concern. The car is fine... but like someone had mentioned when you have a car with this new (new platform , new technology) there are definately going to be some cob webs that can be fixed and cleared but........ I wonder if anything can be done to fix this issue. If you guys remember I had made a big deal about the Hard Starting issue with a few months ago and had posted my concern on this forum for all to read... I ended up getting a upgraded flash from them to help lean out the fuel mixture and a few other things. I have never had the problem yet and my gas mileage has definately improved Its just that in this case I do not know if there is a fix that the dealer can address....to add to that they have to have some sort of TSB from Mitsu corporate to do this.

 

Sounds like it could have been a TCU software bug.

 

The thing is, there is a signal thats sent to the TCU/ECU every time you hit the upshift/downshift paddle (and/or the stick). The delay is the milliseconds that it takes the signal to reach the ECU.

I've compensated by shifting 500R's earlier than I need to. So when i want a redline shift, I'll hit the lever @ 6k and it'll be shifted by the time it hits 6.5k.

Also, (as someone noted before, forgot who) the ECU learns your shift points at the level the gas pedal is depressed. Train your ECU to do proper shifts, and LEAVE it in auto/sport mode and it'll shift perfectly every time.

To train the ECU -
Put it in manual mode, and shift at whatever R's you want in each gear, consistently. Do this 4-5 times, and the ECU will start to pick up on your patterns. Then, when you leave it in auto mode - the tranny will behave however you taught it to. I've currently got my shifts in normal mode @ 3.5k in gears 1-3, and @ 3k in gears 4-6. In sport mode, for stoplight-to-stoplight fun (and when I feel like being noisy), I've got it trained to shift at 5.5k when the gas pedal is 1/3 of the way down.

Hope this makes sense?

 

well said lol. I knew the ECU learns how you drive but i wasn't sure how long it took. thx.

 

^np, .

Also, it doesn't take very much to F up your shift points. Say one or two "whoopsie daisies" in manual and you have to start ALL over! lol.

 

Good point. It seems that the delay is more than just milliseconds. Timing it ( with mild accuracy) it seems like there is a full, whole second of delay. I am wondering............ if I use the manual mode at least once a day ( which I currently do not) and train my tranny by shifting 500 Rpm's sooner than usual, in time will it shift quicker when I drive to the red line and "ask" for the gear change. One second may not seem like much but when you are experienceg the awesome snap gear shifts of the sst but have to wait for it to happen when asked for.....does seem dissapointing.

 

wow, i had no idea it could do that. Definitely worth doing cause i love sport mode but revving at like 4k in third gear for moderately long distances is just unnecessary.
