I just realized that I have resources to make piggyback ECU! Project will be open source so you will have to buy parts yourself and put them all together + install software on controller. It requires some soldering skills (very minor) so I will also offer complete systems for around $250-270 shipped. If you assemble it yourself it should be in $210-230 range.

For all of you who like to brag about me trying to sell **** constantly: as with other **** I offer - this pays me no more then $2 an hour (sometimes I am not making ANY $$ at all) after shipping fees and such!

Features:
- Fuel, ignition, water injection, boost, etc tables (up to 20x20)
- Wideband input
- Full takeover of fuel and timing
- Ability to run any injectors
- Datalogging of up to 8 sensors

Now, be patient - programming for this thing will take me good 2-3 months so don't hope to see it any sooner!

dude, you couldn't handle a megasquirt install, which isn't tough and is well documented.

be real.

 

Sounds good to me, I'll be watching.

well, i didnt build megasquirt and it has all the features which i will never use anyways. its overcomplicated and honestly it is pretty hard to tune if you dont know much about specific car's circuitry. thats why i decided to build a piggyback - let stock ecu run everything and leave adjustments of pulses to piggyback.

 

also, i talked to jerry from diy auto tune. he assured me my settings should work. so far both of us think its a problem in megasquirt itself or wiring. i need to dig into it deeper.

sounds interesting, keep us updated.

 

PC Pro, the next generation?

http://www.makingthings.com/ - this is the controller this piggyback will be based on. It features 8 inputs and 8 outputs. Problem is - it can only take 3.3V inputs so 5V will have to be scaled down and that will reduce accuracy. I think that price will make up for it.

Sensors that are possible to connect:
- Wideband O2 (narrowband is most likely to fail although it's still possible)
- AIT / CLT
- Knock sensor (KnocksenseMS?)

 

not exactly. pc pro is not open source and you cant really set your own maps on it, can you? it will work in similar manner to emanage

I actually know nothing about PC Pro, other than the extent to which people here make fun of it. And that's what I was referring to.

nobody is forcing you to use it if you dont feel confident with it. i am just making it for a sake of it

 

i say go for it!

 

system of a down sucks

 

That is a matter of opinion...And off topic.

 

lol.

And yet, beside what was said about urban being retarded, the most intelligent thing in this thread.

 

i like system of a down. but yes, this is off topic.

 

I detect eminent failure.

 

I'll make a wager that this never gets any further than an arguement on this board. Good luck re-inventing the Emanage Ultimate.

 

Whats wrong with the current piggybacks that are already dirt cheap and have support from multi million dollar companys?
