Sport Mode Autoshift Disable

[speedwave]

When I put my gear in sport mode the car does not hold the gear when RPM gets close to red line. The gear would up shift and its not helpful when driving in the sand.

I am aware that Pajeros after 2011 do not up shift. Any idea how to get my gear to hold in sport mode?

I am assuming this is a programming issue? Anyone has experience in programming Pajero gears?

..I dont understand why you,d want to hold a gear at close to redline..Max power is at 4000rpm and maximum torque is around 2-2500 rpm..Redline is about 4250. I,d be changing at 3500rpm

When driving uphill on a steep sand slope and gear shifts up, car loses momentum fast. I would rather be in control of when to upshift. Has anyone seen this problem on the Gen 4?

3.8 petrol

Dicko,
I think that he's talking about the V6 petrol motor not the diesel that we're used to😁

That's right it's 3.8v6

Sorry mate. Petrol not diesel. Last petrol car I had was a v8 falcon....not very good on sand dunes!!

Not with that attitude!

Hi Speedwave,


The 3.8litre EFI Petrol NS has the Jatco V5A5A 5 speed auto with a 1.6:1 low stall torque convertor fitted and 4.3:1 diff ratios, this is same Jatco auto fitted to the PB/PC Challenger except the Challenger has the 2.04:1 high slip TC and 3.917:1 diff ratios.

On the Challenger the INVECS II AT ECU control has built is "self protections" that limit rpm in certain gears, this maybe the situation in the NS. The trans will automatically shift up a gear when rpm is too high so it could be possible that that the tacho is slightly out of calibration and the ECU is sensing 6000rpm and the tacho is only showing 5800rpm.



So does this only occur in high range or low range or both?
In what gears? 1st? 2nd? 3rd? 4th?
At what rpm does the up shift occur?

What size tyres are you running and at what pressures in the soft sand?

OJ.

Hi OJ

You are right it's a Jatco gear as I checked. I have standard tyre size and this issue is common on 2007 to 2011 petrol gen 4 only.

Is there a way I can reprogram the INVECS II ECU? Do you know anyone that can help or maybe I find a way to alter the tach signal going into ECU to trick it to think RPM is lower so it doesn't up shift in sport mode.

I wish I can just grab an engineer from the factory this is a problem all 2007 to 2011 pajeros in my country are dying to solve

****FINALLY SOLVED*** This is to update that the Mitsubishi Pajero Gear Hold Auto Upshift issue is now solved!

I had my Mitsubishi Gear Hold Programming done by www.speedecu.com

My Pajero now holds the gear up to around 6500 RPM without autoshifting to the next gear. This was done by programming the Pajero Gen 4 transmission to hold the selected gear in Sport Mode (Tip Tronic)

Previous Solution Found on how to stop Pajero Gear from Auto shifting

So two solutions have been found on how to stop the gear from auto shifting for 2008 to 2010 Pajeros.

Solution 1. Omani Gear Hack: Its a hack only meant for advanced users and was initially discovered by the Pajero_Oman team.The Omani Gear Hack works by disabling the output speed sensor which will stop the car from auto shifting. Any mod like this comes with unknown risks before anyone plans to replicate. However, it solves a major problem for desert driving when you need the gear to hold at high RPM and has been in use for the past 2 years with no issues on many cars in the region. I like to repeat anyone planning on placing a switch on the gear output speed sensor will do it at there own risk Having said that the Omani Gear Hack allows the engine to rev as high as 6500RPM without the the gear upshifting on its own and without the RPM dieing when it hits the limit, this effectively turns our electronically limited cars into beasts when climbing high dunes! It unlocks the full potential of the car in a scary way, yet I repeat this solution is far from perfect but does the job of holding the gear very well.

Attached is a detailed guide on how to do the Omani gear hack to prevent/stop your Pajero from upshifting gears in sport mode

Solution 2. Unichip RPM Cutoff: This is the less intrusive solution using Unichip to limit the RPM to 5200. The Unichip ECU piggy back computer with the RPM cutt off option allows you to put a limit on the RPM to prevent the gear from autoshifting in sports mode. Unichip comes with a 5 map selector, so you set one of the maps on the RPM limit at 5200 then car will not upshift on all gears when in tip tronic mode! This is useful for easy drives and smaller dunes. However, if you plan on climbing big dunes and need the full 6500 RPM range then the above Omani Hack solution is the way to go.

I personally run both solutions on my car and alternate depending on how aggressive the dune climb is.

Greetings from Dubai :

Another offroader here trying to get rid of the Tiptronic upshifting problem. I am not so fond of using the Omani hack, as i want to keep the car in 4H, and definitely not OK with having the CEL light on.

I am currently looking at either of those options:

- Going for the Unichip rpm cutoff option.

- Installing a "racing shift light indicator". Would help me getting notification whenever i am near the upshifting point.

- Using a Bluetooth OBD adapter with Torque App, which also have a shift light indicator option.

I am using my 1999 MT Pajero for the more extreme stuff, but wifey is currently using our 2008 LWB Pajero for offroading, and the upshift issue is pretty dangerous while doing sideslopes.

Thanks !

Good day!

Speedwave,

where to source the unichip piggy back in dubai i'd like to have 1 for my SWB 08 pajero, just to hold the RPM not to autoshift while climbing small dunes is enough for me. is it possibe to use 4H 4x4 gear select if i opt to do the omani gear hack mods? im not into extreme desert offroading. overnight desert camp and a novice dune bashing is good enough for me.

Have fun and safe drive mate!!!

Cheers,

Hey man you can search for MOCA in the UAE, they are the official unichip tuners. Just show them my car picture and they will know what to do. If you don't want the omani hack ask them to add an rpm limit at 5200 for one of the maps. This will prevent autoshifting in sport mode and good for easy drives. If you need the full rpm range then i would recommend to go for the omani hack
