I still can't understand why they would put a ball bearing wastegated turbo in the d22 and a bush bearing vnt turbo in the d40... surely they could have thrown a ball bearing vnt turbo in both of them...
I agree with both camo and bods. The Garrett turbo is a mass-produced "it's ok" job, but many aftermarket ones are better (except for Kambrook ones). I think Forefront Industries make one now too?
And you DO have to wonder why they chose journals on the VNT model. The bloody thing spins at 100,000rpm+, why on earth would you use metal sleeves as bearings?
VNT control does require some extra processing power though and maybe the D22 has a Casio-based ECU compared to something by Intel (a very early one, jeez let's not get carried away) in the D40.

Good point with the ecus tony. I'm still looking into software to have a play, the most I have discovered so far is they are both denso sh078 based ecus. I know mine definitely has a denso ecu in it, I have removed it and even took a pic hahaha. Actually getting software to talk to the ecu is a different matter entirely...
I've got Scanmaster here, I have to bodge up my OBD adapter so I can not only query the ECU, but write to it too. Just getting some extra renovations done to the new house ... we are moving in 4 weeks' time and I'm now ripping up the carpet in the bedrooms!

Wow... sounds like fun, or not... better not get too far off topic hahaha.
Join ecu-connections.com and google mpps clone and see what you find. mpps might not be the right one for denso but it'll point you in the right direction. WINOLS for the mapping.

Already on ecu connections, but I'll have a look into the other one. The biggest issue is finding out the access keys to start communication. ...

Yeah, seen his thread, but not a lot evolved from it...

Was the the sweedish bloke?

Yeah I think so. Someone did post a d40 definition file on there, the problem seems to be actually communicating with the d22 ecu... :/

You dont see much ecu flashing for d22s advertived...is it actually available?
bods
Member
Yeah, well as far as I know it is lol... that's why I'm trying to do it myself lol

If its nissan updateable its hackable!!

Yep, that's true. Just a matter of working out the maps. The main thing is disabling egr altogether and having a play with injector timing and duration

so the remapping basically does what a chip does
bods
Member
That's correct. You are just editing the factory maps in the ecu instead of putting a chip in between the motor and ecu...

and when u do a reset of the ecu the new settings stay?
