http://www.ebay.com....E:X:RTQ:AU:1123

I just cant believe it, but its so hard to resist at this price (which is what they are counting on...) But even if it adds no performance, and simply increases my fuel economy around town, it would be appreciated (even the wording says "average", meaning some could be none to negative). But the thinking part of me is jumping up and down yelling :pirate: SCAM! :yucky: SCAM! :down: SCAM! :rant:

Has anybody tried these? or even know a "friend of a friend"....

December 2009 : click the Linkage

I have seen these things on Ebay before myself and was curious but having searched on here, decided SAU knows more than Ebay.

Q: Hi I am interested how this chip works?

A: PROMAX X-CHIP connected directly to ECU sensors (MAF/MAP/IAT/O2) by playing with this sensors we can change ECU stock parameters.

Ummmmm..... So it tells the ECU lies about what is actually happening with the engine. Causing it to run leaner or richer than it was originally designed to. Sounds like a great idea :happy:

I love the bit where it says that it does not void the warranty. Imagine taking that back to the dealer and saying that the engine leaned out and you want a new one replaced under warranty :rofl2:

It is not a scam, but simply is a resistor which decreases the voltage signal of air intake in the AFM to the ECU, and so makes the car run a tad leaner and make a tad more power. Problem is the ECU will probably re-learn that it is there over time and not have any effect.

Either way, don't risk blowing up your ECU (or worse, engine) on one of these pieces of crap.

Go out and buy yourself an SAFCII ($400) or Apexi Neo ($600) and get it tuned properly ($300-$500). Does a similar thing (in theory), but professionally, with significantly more scope and complexity, and your tuner can perfectly tune your afrs to maximise power and fuel efficiency.

thats exactly what happens. save yourself the money/hassle/problems and keep your money for a proper programmable ECU and do it properly the first time.

That's how all interceptor ECUs work. And, even with a standalone, you're basically doing the same thing (not lying to the ECU, but causing it to run richer/leaner than the engine was originally designed to).

The difference is that this thing isn't tuneable, so you're taking a massive punt on whether its too conservative (and does nothing for your engine) or too aggressive (and causes detonation).

    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
    • meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)
