I saw this pigyback ECU on the web, can some one tell me about it, and how different is it from the others, like SAFC, XEDE, U-TEC ????

Its not expensive either

 

Try this too, this link might help http://www.ecuplus.com/index.htm

 

? Any one

looks good to me...although for a few hundred more, you can get the UTEC which seems to have more features...

ill have to read up on this some more...i would also like to hear from people who have experience with this system.

 

I think its a great option and has some cool features.. It does use timing offsets and MAF offsets and it doesn't control boost.. It appears to be similar in function (with a few new cool features that almost nobody has) to a few of the existing products out there.

I have not tried one, so I cannot really tell you much about it, and I don't know of anyone who's using it so I have no opinion to base it on for you.

The UTEC is just functionally Different than this device.. But its similar in some ways to all the piggybacks out there.

 

kind of reminds me of a Unichip. Since it only controls fuel and timing, it's perfectly legal for ESP in atucrossing.

 

Any other input guys ?

 

? any one has ECU+

 

My freind has one on his evo and it seems to work very well. The datalogging features and pretty good aswell. It is a very cheap alternative to the e-manage and the s-afc for being in the same price range. It will soon have the ability to monitor knock aswell, which seems to be a big plus. And the ecu plus also has features where you can setup other devices to monitor boost pressure and soon knock.

 

This statement off of their site scares the bajebus out of me...
"Alters the MAS air-flow signal up to +/-50%, which modifies the engine fuel flow"
This means that it fakes the ECU into thinking there is more or less air flow to modify spark and fuel. I run from this one screaming.

 

You might want to have a look at the forums I've got setup at forums.ecuplus.com. See what some of the folks who've got the ECU+ have got to say.

How come? This is how all of the piggybacks work - the HKS Super AFR, the Apex Super AFC, the Vishnu XEDE, and (I think) the GReddy eManage. You have to switch to a standalone like the AEM or the UTEC to get a system that controls the injectors directly, at considerable extra cost.

Does that mean it's the right way to control?
Do tuners use this type of control or map modification?
I would pay extra to really control rather than pretend to control.

 

Whether modifying the MAS signal is the "right" way to control fuel or not, it's certainly a technique that works for an awful lot of cars. A guy I was talking to last year at the local track was using a Super AFC in his 10-second Talon, so there must be something to it! I guess the bottom line is that if you absolutely want complete control over your injectors, and are willing to pay $1000 to get it, then the ECU+ isn't for you.
