Megasquirt m52?

[318isbmw]

megasquirt doesnt offer very good engine control... a lot of people blow engines because they dont really understand what they are doing with megasquirt

Then howcome people are able to in e36's run m52's w/ 600+hp w/ megasquirt. I think its all in the tuning and how good at it people are.

you exactily correct... the guy on bimmerforums that runs megasquirt is an electrical engineer and has basically reengineered the system to run the engine and even still he is constantly fine tuning... how good are you?

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


BINGO!!!!



And how are you going to run the coils? I only see 1 coil driver in megasquirt.

You put 5 more coil drivers in.

LOL

ignorance...

Ignorance? No, when you buy the megasquirt kit, it only comes with one coil driver. That's why when you place your order, you buy 5 more of them. Once you receive said products, you must solder it all together. That's when you put the other 5 driver's that you ordered in place.
Have you read any information on MegaSquirt?

I wasn't talking about you, sorry for the confusion. that's exactly right.
alternatively, you could just run wasted spark with 3 coil drivers, which is just as effective. but that's not good enough for most of the elite 24v guys. :p

[techno550]

You have to run wasted spark with MS anyway. if using the stock coil packs on the M5X motor you also need a total of 6 coil drivers.

wasted spark doesn't hurt efficency like non-sequential injection does.

people have performed various tests with seq and semi-seq injection... and found there is very little difference in terms of efficiency.
seq injection is good for minimizing the total opening time though, and thus has a much larger useful range of injectors' flow rates (nothing an RRFPR cannot fix).
seq inj should be coming to MS2 near you sometime around Christmas when the router board is out

I'm not sure you that really want to start a "discussion" like this.

Not that good, but just cuz I'm not doesn't mean I can't learn. Never learn by sittin back and watchin others. And I believe its more than one person on bimmerforums running megasquirt with success.

[StereoInstaller1]

Never learn by sittin back and watchin others.

bad advice right there...ALWAYS learn from others' mistakes.

Maybe I should not point that out to you, so I can learn from yours, eh?

Just funnin'

you are right, this discussion is pointless without solid experimental (not just theoretical) proofs. I'll see what i can find.

I am going into "if you can't say anything nice..." mode now. I won't post in this thread again. Good luck.

PFFT, how dare you knock a 400 dollar home-brew replica of an early 80's GM fuel injection control system.

Can you load a 32 x 32 fuel and spark table in it also?

[PiercedE30]

Well, if you use the table switching of MS2/Extra then you get two 16x16 tables which equals what? 16x32
You can also set when it switches over and under what conditions.
