Cool then, keep us posted I'm very interested in a turbo setup ECU.

 

Well, it HAS been done though.

I've got a link for a website with the HARDWARE and SOFTWARE to let you reprogram your ECU thru your ODBII port.

I showed it to Random awhile back.

I'd be stocked to see it happen though, I'd love a good ECU solutuion.

Tim is working on something similar too.

 

hmmm... there is a way to made the SAFCII boost sensetive...

its actually quite easy.. and I have read of many people doing this mod.. I think they call it the SAFC HACK...

Basically, all you need is any aftermarket map sensor, 2 bar is a good choice..

then, when you install the safc you DO NOT connect the TPS sensor to the tps, instead, you wire the tps signal wires to the 2 bar map sensor.. in effect, the SAFC will adjust fuel trim based on BOOST.

This is also very useful because it is dynamic, no more running lean when going down a hill and stuff....

You are all welcome.

 

fordfasterr, the discussion on HA.com about the boost referenced SAFC was in most part between Red and me. Red made me understand in that discussion why it is NOT such a good idea to use boost as a reference, and why it's far from being "magical".

/Edit: I just seen that you were the one to start the topic wink1.gif Funny. Still a VERY good topic, with lots of information and arguing, just like this one wink1.gif

I think that discussion actually got me thinking about reprogramming the stock ECU wink1.gif

Boost referenced SAFC on HA.com

Redzman, it would be great if you could dig back that link/company. The problem is that reprogramming the ECU through the OBD2 port is by no means "standard", altough most newer cars can do it. A general software/hardware can't do it. You need to know the specific protocol of the specific ECU. It is possible that a company actually got it to work with Hyundai's, but I have my doubts wink1.gif

Might I ask who is "Tim" too? If he's working on something "similar", maybe we could look into what we could share.

 

And who said it wouldnt work just fine ?

So far, some people are using it and it works. How can you disprove that ?

I guess we will have to find those people and ask them more questions.

 

I *never* said that it didn't work wink1.gif In fact, I *know* that it works, but I know too that the advantages versus using the TPS are almost non-existent.

But you can also get a turbo car to work with an FMU, and by upping the fuel pressure like mad; you can mess with the IAT sensor to get more fuel; you can advance timing by disasligning the chain with the gear, etc. There's a lot of ways to do things, and most usually *works*; but it doesn't mean there's no better way wink1.gif Some people just want stuff to work, and that's fine. But I like things to work the best it can. And that's fine too wink1.gif

 

well, if i wanted to have a system that was "tuned" ... I would definately want a controller that is boost dependent..

 

No. Boost is irrevelant. Airflow is what is important. In a MAP-based car, the MAP sensor is actually used to calculate the airflow coming in. On a MAF car, the sensor is used directly (after being normalized).

We already had that discussion in the topic on HA.com I pointed out. I won't have it here too wink1.gif

 

well you are entitled to your opinion.


lol


even if you have no basis to support your theories.

If you say so, must be true :roll:
