E46 320d mapping

[hillclimbmanic]

Hi there!
I've just returned to the fold, after a few years absence...2 E30's an E36 318is, and now I've just bought an inlet flap-damaged E46 320cd

After sorting out the mess, rebuilt head, pistons, etc...and of course, removing/blanking the flap
system, my thoughts now turn to upgrades...I'm currently restoring a TVR Griffith, so a 4/5 seater makes perfect sense, as an every day car!

Thoughts on the EGR delete, Cat front pipe removal, mapping etc.???

Regards,
Paul

Do it! My old 330d had those mods and it made a quite a difference to the power as well as making the torque delivery a lot more linear which made it much nicer to drive. It also improved the fuel economy, which was nice.

I would definitely recommend EndTuning for the remapping side of things http://www.endtuning.com/. He did my E46 320cd and with a decat downpipe made 212bhp on the rollers. Car had already done 117k before the mapping and just got rid of it at 170k. Not a single issue with the map.

Don't bother removing the egr. It works well. My 330d still has the original egr valve at 244k miles, tried a bypass but got less power and worse mpg.

Can't recommend Enda at End Tuning enough.

Worked on my 330d after decat, egr blanking. Made a nice usable difference to drive ability, much more responsive and didn't run out at points where boost would usually be done.

I wasn't chasing numbers and didn't push it too far as I am on stock gearbox and clutch but the rough figures were approx 255hp / 500nm.

Also saw a fuel economy increase overall - easy seeing 55 mpg on a steady motorway trip.

I'm 10k miles down the road and had zero issues, so he comes highly recommended from me.

Thanks Guys! Quite an easy decision, then?!!!
Because I rebuilt the motor, that had already been stripped down, I put all the spaghetti and vacuum pipes back, blind...Hopefully, End can tell me all these things, as well.

I've fitted an EGR bypass, without the delete at the ecu...As I've never driven one before, I have nothing to gauge it against...It did feel flat, compared to my Mondeo 130bhp model, so this could be the reason why?(edit...it is freeing up a bit, and is getting more responsive, after 1,000 miles of running it in)
I've had the EGR ultrasonically cleaned, so maybe I should refit it?
One more thing...Does anybody know if the cams are different, on the 150 PS, compared to the 136 PS.??

Thanks for that, Helix...I'm going to refit the cleaned EGR, and give that a whirl.!!
