but Mitsu was on my way to work and supposed to have the right stuff on the shelf so rather just went there. Luckily they had stock
Cats could you maybe help clear this up for me..correct me if im wrong but the Gen 4 injection is controlled by the ECU where the Gen 3 is controlled via mechanical timing. If you remove the cat from the Gen4 , the ecu will get incorrect mixture readings and will try to compensate for this change and begin to run rich. I know this happens on petrol engine engines and usually remapping is required but dont have a clue with Diesels. Have you noticed a consumption change? Also is there any effect on the Gen 3 ?CATS wrote:So decided that the cat converter has done enough work at 160000kms and had it taken out. I don't think it was really radically blocked. Will see if it makes any difference to performance or fuel economy but not expecting miracles. Just helping Casper breath a bit easier and getting rid of old gasses easier.

On both my previous gen 3 and current gen4 I cant say that I noticed a material change in power or fuel consumption after cat removal. Definately more noticable turbo whistle and more pungent diesel smell from exhaust though.JTEC wrote:Cats could you maybe help clear this up for me..correct me if im wrong but the Gen 4 injection is controlled by the ECU where the Gen 3 is controlled via mechanical timing.

Ok great thanks. I have been keen to remove the cat but was a little concerned. Just another quick question, would you recommend blanking the EGT ?CATS wrote:On both my previous gen 3 and current gen4 I cant say that I noticed a material change in power or fuel consumption after cat removal.

Does seem to rev easier but might be imagination.
I dont think the gen3 or early gen4 has sensor on or after the cat, so it will not pick up anything different on the ECU as there is nothing to measure. On later models there are apparently sensors which will throw fualt code if you decat.

The gearbox was only done as extra maintenance as I tow every now and again when I go away and still feel a bit weary of these autoboxes after having driven a manual Pajero for so long.
MAF sensor was also found to be faulty and was replaced.
Must say it feels more powerfull. Will check fuel usage but can't wait for the real test when I go camping again.
Attached is the dyno report.

Definitely better than R11k from the dealersCATS wrote:Second hand they charged R2500 for the MAF sensor, which was ouch after the service, dyno and gearbox service, but I think in line with pricing in the market.
