I was between this and a Haltech....Ended going Haltech cause I got a killer deal on it. Can't go wrong with the AEM unit. All the fail safes are worth every penny IMO.

 

I've been considering the infinity as well

 

$600 retunes? Holy ****

Anyways. The Infinity is a solid upgrade. You will want to change the crank trigger out for a 12 tooth though (for best startup, as well as full knock control), kiggly sells a kit. So, you'll have some work to do besides just installing the ECU. But if you have the cash, I would definitely say go for it.

 

 

If your paying $600 for re-tunes, you would be best served by learning to tune. Or at least to make adjustments from a baseline to fueling after changing things.

 

A stand alone wouldn't need retunes. It can run full time closed loop (AFR targeting), and you can just adjust boost from there. The infinity also has a map switch with the ability to switch between 10 or 12 maps on the fly. So, it's a much more one and done type deal if your engine/fuel system/turbo doesn't change.

 

 

Not sure. I've heard of people paying more for less lol

 

How good is the AFR targeting on modern standalones? Is it only useful for feedback on dialing in maps? Or do people actually trust it full time to manage their tunes?

 

The car should still be fully tuned. Kind of like the stock ECU has closed loop trims for idle and cruise, but you still tune the car to dial those in to get pretty close to zero. Withj the stand alones you can choose to run it in open or closed loop, and you can choose how much range of adjustment it has as well. It's certainly very capable. If running full time closed loop, I would have the oxygen sensor be part of the routine maintenance schedule for replacement.

 

Will it interpolate surrounding cells that are hard to get when dialing things in but may be seen in areas like on a road course? Stuff like high RPM with low load (holding speed in a sweeper for instance). I dont know how well the autotune stuff dials in cells you dont hit often or easily. Also, it makes music sounds stupid

 

$600 for retunes? Damn I am doing something wrong with my pricing then... I'm almost afraid to ask how much the initial tune cost.

Anybody adept with AEM, MOTEC, etc would probably charge less to *re*tune with them as they are a million times easier than most Mitsubishi stock ECU's.

It's really a bummer Mitsubishi never went to wideband closed-loop strategy.

Tuning my Fiesta ST is so much easier than Mitsubishis.

 

I just made a video where RS motors touched on using the AEM infiniti stand alone.
(time stamp, 5min 4 seconds)

Ronnie spoke more about it but i cut it down for time. Ronnie though one of the biggest advantages will be how easy it is to adjust boost setting to control power level for track different conditions.
Probably just a good race team for you to follow and see how they progress with it since its new to them.

 

Are there two triggers (cam and crank) or just one? Thanks for the kiggly tip. I can't believe the AEM/Infinity kits don't come with these included? I have asked several of the vendors sales reps and none of them have been able to answer this question. LOL!

Great RS video! Thanks for sharing. Always learn a lot from you guys. Can't wait to meet at an event. Might even let Smedgard behind the wheel of my car. Ha!
* Great to hear $600 re-tunes on stock ECU are a shock to all of you too! I think repeat follow up tunes run me $500 locally who uses a E-tune service???
* These prices push me towards the AEM/Infinity stuff, but learned today English Racing priced me at $5000 and said it would be $1000 for base stand alone tune???
* This makes an initial $600 new engine tune on stock ECU sound great afterall.

Probably just run the stock ECU tune until I can recoup some savings after this latest round of upgrades. Whew!

After jumping off the cliff and getting the Dry Sump, 4g64 block, knife edge crank, pistons, etc.....Whats another $6000? Clearly I am in the wrong business. My NASA, Bio-Chem, and MD degrees don't profit as much as ECU systems and retunes. LOL!
