ECU Tuning from Calvin

[supergripen]

wow..that's a powerdyne head unit rite? so what kinda hp he's pushing?
if u dun mind,can u pm me the cost/price? i've still got a few issues to take care of but its coming..SK1.

hi zoggee..i recall we talked about this in another thread.if u don't mind can u pm me the parts required and price as well(incl labour)?
u know anyone who can do this?? i'm going to Obermaier tmoro to have a chat with Simon..just a chat la.want to get an idea of how the project would be like.

unker simon would advise you not to mod(force induction) the M52.hehe...to save you money on maintenance.

btw,whats ur engine...issit running on e.m.l(drive by wire) or same conventional throttle body from M52B28.???

 

[supergripen]

i'm gonna talk to him about swapping the gearbox only..just to have an idea of what's involved.its never the same when u talk to a few people..gotta formulate ur own ideas.

anyways,mine is a 2000 e46 328i m52b28tu..not sure if its drive by wire.steptronic A5S325Z 5HP19 ZF gearbox..not sure what the manual shud be,Getrag?? dunno..

the M52B28TU is not drive by wire..its conventional cable..only hte M54 engines were drive by wire...apologies if i am wrong..

heyCalvin,sorry..'ter'hijack!!

wow,thanx Zoggee.so its still a ZF.desig S5D320Z.. so is it possible to do the swap? other than the obvious,i don't have to change the ECU and the ABS rite??

wonder how much the cost?

hey i'm confused (again!)- how can they tune the car offline from another country?(telepatic powers aside).

i read somewhere the act of tuning implies either via an engine dyno, chassis dyno or on the road or a combination of some of the above. and in all instances there is judicious use of wide band lambda sensors and a knock sensor feeding an amplifier and then headphone on the tuners head.

or is it that they have some standard off the shelf maps for specific engines that they have tuned in germany and they can dial in some minor adjustments to his base map?

Yes, the above is correct.

 

[fabianyee]

For a next to perfect remote-remapping, u need to provide:-
1. the current ECU mapping.
2. Dyno chart with Air/Fuel ratio along with HP and Torque reading.
3. List of mods done.
4. Possible future upgrades.
5. what do u want the new mapping to be. Mid range torque? High end gain?

icic, thanks calvin!

fabian, the slight annoyance with dyno plots is that they only represent what happens under fixed condition(usually wide open throttle).

i suppose if we optimise based on this curve and we only drive at WOT all the time then it will be optimal.

but dyno plots don't tell us what happens at say 20% throttle, or, 65% throttle. so if we have a curve that says at 5000rpm the on wheel power is 150hp, that would be at WOT. conceivably at 20% throttle it is a lot less but how much so? and what is the lambda then?

and then there are car specific items such as condition of fuel pump and injectors, ignition coils and ignitors, even spark plugs right down to gapping that influence how much is too much. also grade of petrol, and air conditions.

of course what i have mentioned only comes into play when you are really pushing at the edge. car manufacturers tend to err on the safe side with a lot of margins such that these factors will drown in the noise floor. but i always have an impression of the word tuning, to really be, fine tuning and custom. to really squeeze every drop out and not throw the towel in at 1/3rd turns.

f8,

Everything that you mentioned is true but how many owners are willing to spend their time to do on the road mapping / tuning. Only hardcore will do that. Alternatively if you have money and don't mind to spend it ( a lot of it)for somebody to tune your car on the road, than the remapping using others base programs or dyno chart for full throttle application will be enough for most driver. Racer nak main kat Sepang bole la, normal driver no lah.

Rgds.
