About Help with D4D intermittent stutter/ miss
I have a 2011 prado with this hesitation issue,
i have had it re mapped about a year ago and still she the issue, but unsure if the where about to update the ecu for the upgrade. Not really sure how this works though. And it’s around 2000-2400rpm she jumps in and out of hesitations. Would the temp have automatically updated this or is it something that only Toyota can do

this was fixed with a Toyota ECU update

Any changes to fuel consumption for city driving after trans flash?

Not that I noticed

[Riv39]

Rob, yeah only affects the auto as it makes it hold 4th till approx 60km/hr.

Rob, keep an eye on your fuel economy around town...oops just noticed you've got a manual. The economy issue only affects the auto.

Good point even though its a manual I will keep an eye on it, but in essence so far I can't see any change. Overall I'm glad I've done the upgrade.

Hi Guys,

I think I have this miss issue at high speeds on slight inclines (slow acceleration) at around 2300-2400 rpm. Its a very quick pause almost enough not to notice but its definitely something along the line of this issue. Mine is a manual, I'd be interested to hear if any manual drivers have had the ECU flash done and any improvements ? Also I assume there is no way to check the current ECU version apart from taking to Toyota ?

Rob

I have a manual, had this problem and Toyota did the ECU reprogram and it's been fine since.

after 6 months on the new firmware, (and 20000km) we haven't had the issue. no more hesitation, etc. economy is the same.

avoid lane toyota, they are lying asshats

Just an FYI I had the update performed last week by a Toyota dealer, even though my car is out of warranty they were really good to pass the cost back onto Toyota Australia, hence free upgrade. I have noticed since the update, the car is much smoother between gear changes and just nicer to drive, I still need to do a longer trip to see if I can replicate the issue (hopefully not) but I'm pretty confident the problem is solved.

G'day

My 150 just started this stutter. I have owned it for nearly 2 months. The used car warranty just expired on my recent road trip, It has only started playing up todayf. It's just due now for 120k service. I have noticed this stutter when acelerating, mostly at higher speeds. Pretty annoyed.

The update should just be a part of servicing so no cost.

Is your problem related to how full the tank is at all?

[Ticka]

Yep mine was ok for a week after the flash now its back to the usual 2500 rpm slight stutter. If I flick it across to the sports shift its completely gone.
Not overly noticeable anyway so ill wear it until a better flash is released.

Cheers
