Limp mode and surging problems

[269LUX]

hey guys i have the same issue every now and then when i back off the throttle i get limp mode. just turn the engine off and start again on the go and its all good. quite irritating but i love the power.
Very interested to follow this thread and see what the experts think.

Hi all, I installed a tunit last Monday. Power was incredibly increased. Drove it for a few days without a problem, then heading away for Easter towing a tinnie , my 05 sr5 went into limp mode. I tried turning it down one setting at a time (normally on 6) but kept gettin limp mode unless on setting 0 which defeats the purpose of a chip. I'll have to see if it's the extra weight of the boat, speed or what it is.

Guys any chip that plugs directly into the fuel rail sensor is going to give you grief at some point in time as its electonically raising the already incredibly high stock rail pressure and giving you the limp codes thrown and other nasty things going wrong.

I know the Chip-It does plug into the individual injectors aswell as a plug to the rail sensor which is why the problems arent as common as the DP chip or other ebay style ones which only has the one plug that goes to the rail.

Not bashing them im sure there are people with the unit that havent shown any problems yet but and have got alot more power out of our d4d, but im pretty sure something will go wrong at some point in time with it, putting a metal spacer into the fuel rail itself to stop the problem? What hell is with that it doesnt sound like a very good thing to do at all altho im no mechanice and happy to be shot down n flames if its a proper way of fixing it but sounds like a bloody bodge up to me! Just my two cents fellas not bashing anyone

Look at blokes running the steinbauer - vmn or i think diesel smart modules - no problems cause there not touching the fuel rail pressure at all, i know they dont make 70% more power than stock but what good is that when your overtaking a road train on the hwy and the thing throws a code!

Hi All,
Just got back from my Christmas holidays and I too am having similar issues.

I have a 2011 HIlux SR5 Auto and had my Chip It installed 3 or 4 months ago by a Chip It Installer.

The problem we are having is it going into limp mode. It happens when driving with Cruise Control on and most often going down hill. It has happened 4 in the last two weeks, 3 of those last night. The car starts to slow immediately when 3 lights come on; The vehicle stability light starts flashing, the traction control light is on solid and the engine light is also on solid.

The only way I can clear this is to disconnect the battery and wait 5 or 10 mins

I have the exact same problem with my 2011 d4d sr5 auto .but I don't have a chip installed have spent the last 2 days at Toyota and all they can come up with is that there is a fault on the speed sensor on the back of the gearbox .the surging is unbelievably a pain in the ass it only occurs when in top gear and under 70kph. Tomorrow will be day 5 with the same problem and day 3 at Toyota

I think it might be time to change your sig line Diddy

Like u wouldn't believe mate

Car fixed . It was a plug on the top LHS of the gearbox that had caught a stick and came undone

3 days to find that?? Must have been using a blind apprentice.

[Diddy-Lux]

Tell me about it mate. $535 for my troubles . O WHAT A FEELING

[Hellbound]

Glad it was that tho and not a gearbox rebuild, like mine now has to have - 50,000km and its whining big time in first 3 gears. Covered under warranty of course but they need 3 days to do it!

Good to here they found it for you diddy.

An update to my issues. They posted me out a new plug with a capaciter and diode in it. Iv driven it for 3 weeks and no limp mode. (although now the srs warning light is on all the time! They said it has nothin to do with the chip as it does not effect the ecu) On setting 6 I pulled 12.5l/100km which is 25% increase, which they told me to turn it to setting 5. I now do 10l which is what I was getting in the first place, now I just have more power.
Now I'm just a bit concerned about the warning light...
