Pajero tuning advice needed

[Abdullah A.]

Hi @GauravSoni I was searching the topics here on the Unichip and gear hold issue for the Pajeros. I have a 2009 LWB 3.8L engine, pretty happy with it until it comes to climbing hills or soft sand ridge riding then i feel the weight overcomes the power specially when i hit a soft patch and the RPM goes beyond the 5000+ and the gear shifts to 2nd.

Can you share some details around the Unichip and if it's really safe to do it? also there's a lot of people online claim they can do it but is there a reliable place that can do it correctly?

 

Thanks for the help.

Hi @Abdullah A. UNICHIP works for me quite well to overcome the challenge that u are currently facing.

You can approach the UNICHIP authorized dealer. They do the work quite well. 
 alternately you could also try to get in touch with few tuners who do ECU remapping. I would tend to be biased with UNICHIP as I have been using it for last 4 years.. gave me issues with MAF sensor, but once I fixed the intake (snorkel) , it kinda fixed the issue.

Hi @Abdullah A., I have my Pajero remapped done on May 2023. I am not using unichip, so it is 100% only the software/flash file. The modification are:

- Throttle response with faster ramp up time

- RPM limiter removal

- Engine derated speed removal

- Gear Hold / 2nd gear autoshift up removal

I did it when my car was still under warranty, and I have no issues with the car, the km now is 88k, I still use factory fitted MAF sensor. However I bring 3 MAF sensors for spare because of @GauravSoni story 😅
