shardaerithes Posted April 19, 2017 Author Share Posted April 19, 2017 You would want to have requested torque ramp up more slowly at lower pedal angles but go to higher values at high / max pedal angle. That gets you better resolution in part-throttle and upshifts occurring at higher rpm and with more firmness at WOT. Most tuners can pull this off, though there are only a few of us working with the Calculated Torque tables, which is what really rounds out the shift firmness. Is there anyone nearby that would offer that level of tuning for the 5EAT?

shardaerithes Posted April 19, 2017 Author Share Posted April 19, 2017 Pompeii is right around the corner from me and is offering a reasonable cost and I think it would be better to be tuned in person in any case. I think I am going to just stick with stock everything right now and get the car a basic tune instead of worrying about more mods. I don't want to blow up the 5EAT. I mean, is a VF52 + Stage 2 going to overheat and wear out my trans? I need a grocery getter more than a race car right now. Link to comment Share on other sites More sharing options...
fahr_side Posted April 19, 2017 Share Posted April 19, 2017 Not too many specialize in the 5EAT cars, at least not in the US. Auto trans is more common in ADM and EDM cars so we do more of them. AFAIK only throttlehappy and I are taking the time to tune control of the transmission in any methodical way, or at least we are the only ones only discussing it. As to overheating, a trans cooler is always recommended but the most important thing is shortening the time taken to complete upshifts, reducing the heat generated at the source.

shardaerithes Posted April 20, 2017 Author Share Posted April 20, 2017 I'm leaning toward just getting it tuned in a stock/stage 1 way and just not taking advantage of the VF52 fully right now. The trans being an unknown is turning me off without the valvebody mod, I'm worried 280whp will be too much. Sounds like I'm not going to get 5eat modifications done right in software. Any thoughts?

fahr_side Posted April 20, 2017 Share Posted April 20, 2017 I have run several 18G cars to 335whp on the stock 5EAT and one 5th gen with an EFR7163 to 408whp / 55kgm. The valve body is however a great mod and it's awesome to have this option on the '05~'07 models.

shardaerithes Posted April 21, 2017 Author Share Posted April 21, 2017 My 5EAT was supposedly rebuilt 20k ish ago but are there any telltale signs of wear? It doesn't slip, it locks into reverse hard, it sometimes clunks on the downshift to first as I'm on the brakes. Shifts seem good for an automatic but I've not had one in a long time. Sometimes I argue with the tcu and the dbw! fahr_side, did you run those 18g cars without modifying requested torque in the ecu? Or was that tuned somehow. I hate to think of the clutches slipping on engagement lol. I read into requested torque for a bit, it's kind of making my head spin. Link to comment Share on other sites More sharing options...
shardaerithes Posted April 21, 2017 Author Share Posted April 21, 2017 Edward at XRT seems to offer a tune for the 5EAT - any experience with this? Link to comment Share on other sites More sharing options...
fahr_side Posted April 22, 2017 Share Posted April 22, 2017 I modify both Requested Torque and Calculated Torque even on stage 1 tunes. The stock settings are really tuned for a smooth luxury feel, not performance or longevity. You also can PM me with questions.
