I have had both versions of the AEM in my Supra. Version 2 was better, but they really had problems with the auto trans settings. It is very difficult to get the settings just right. They never did get them right. I replaced it with a ProEFI, which has been much better.

With the complicated trans the GTR has, I hope they don't have the box controlling it. I'd be wary of it, unless it lets the stock computer handle all the shifting, etc.

What a waste of time and engines. The Cobb is just fine, it's nice to try and squeeze more ponies out of our cars but not worth the risk.

Can you tell me how the Cobb differs from a new standalone? I'm assuming it piggybacks off the stock ECU?

I think the issue with any standalone is the driveability of the car. There is no way a standalone will be as good as the stock computer for many things. But, it allows you to tune for things the stock ECU does not allow. That's the tradeoff.

These type standalones are great for the full time track, and dedicated race car, for everything else the Cobb can't be beat.

Most of the stand alones require you to have a cobb anyways for trans operations ... At that point it depends what features the stand alone product offers and the price. Sofar pro EFI has proven very effective... How will AEM manage to fit in? Unless its really cheap and or offers trans control without cobb I don't see it being a viable product to make. It will be good to hear more about this product to get a better understanding of what is going to bring to market before assuming tho.

Its similar to the ProEFI. They are targeting MKiV Supra as the number 1 plug and play application, with R35 coming a short time later. Its at least 6-9 months away for us.

It has the Ethanol Sensor input, Traction control, closed loop O2 sensors ect.. I spoke with some of the engineers at PRI, its a nice box.

Edit. Its not really cheap.

Just heard they released the Supra version of the AEM infinity-10 ems. i have not found anything on the R35 development at all. will it be an infinity-10 or 12? costs with sensors will probably be 5000-7000 depending on what sensors you want plus the advanced tuning package. if its an infinity-12 it may be more. with those larger builds using 12 injectors, im thinking a 12 is going to be needed?

AEM has entered into a long term mutually exclusive contract with EngineLab (EL) to co-develop advanced generation ECU's.

EL is a technology company whose patented developments provide the most sophisticated embedded state management system possible by providing a complex method of data management with precision real-time control. With their technology, complete engine behavior models can be constructed and executed dynamically.

The Infinity Tuner PC Software shown in the screenshots below is a new ground-up development authored by both AEM and EL programmers which has never been released, so you couldn't have used this software before. However, in some ways it is very similar to an earlier PC software package that EL created for use during their development program.

The Infinity-10 is the first product resulting from this collaboration to create the most advanced ECU's ever imagined.

CLICK HERE for plug & play applications that include a vehicle specific adapter harness

InfinityTuner USER INTERFACE SOFTWARE
InfinityTuner features custom layouts, an ECU Setup Wizard, and data logging playback mode where all controls are synched to the logged data. This allows you to edit calibration data exactly where you need to and minimize your tuning time. AEMdata data logging analysis software is also included.

AIRFLOW MODEL BASED CALCULATIONS

Infinity system base models are airflow based and feature various modes for calculating air flow. This eliminates many of the lookup and trim tables (Correction Tables) which are necessary in previous generation ECUs.

FUEL CONTROL & IGNITION TIMING

The Infinity EMS calculates injector pulsewidth in units of 1/10th of a microsecond (0.0000001 second) and has NO practical crank tooth resolution limit. The Infinity's back-end timing code is tested to 100,000 RPM.

DATA LOGGING

Log 10 channels at up to 1KHz, 20 channels at up to 500Hz or 100 channels at up to 200Hz standard. Log 100 channels at up to 1 KHz using a high performance USB flash drive (not included). An included 4GB USB memory stick can be replaced with one up to 64GB. Users can also log direct to the PC at up to 500Hz.

DUAL INTERNAL WIDEBAND CONTROLLER

A built-in 2-channel Bosch wideband controller with automatic closed-loop heater control optimizes sensor performance and reliability. Full diagnostics software ensures reliable operation.

FLEX FUEL COMPENSATION

The Infinity's core control model is designed for flex fuel compatibility. It makes automatic adjustments for ethanol content and applies them to fuel flow, ignition timing and boost target (ethanol content sensor is sold separately).

MULTI-FUEL CAPABLE

The infinity has the ability to run two separate fuel types simultaneously through staged fuel injection.

DUAL KNOCK SENSING

Dual knock signal conditioning circuits allow for precise measurements of knock levels.

INTERNAL SIMULATOR

A powerful input simulator feature allows the user to simulate operating conditions. This allows users to validate tuning changes before running the engine.

REAL-TIME ADVANCED DIAGNOSTICS

The Infinity's diagnostics software constantly monitors signal and current quality to alert the user of an issue before it creates the potential for engine damage.

INTEGRATED ENGINE PROTECTION STRATEGIES

Available strategies are based on boost fuel cut, fuel pressure (injector flow compensated for variations in pressure, sensor required), oil pressure, RPM (rev limiter), coolant temperature, knock control with feedback and lean protection.

NETWORK INTERFACES

Infinity is AEMnet enabled and will communicate with another AEMnet-equipped device and output to 3rd party dash/logger devices (not all 3rd party dash/logger devices may be supported).

Always good to see increased efficiency from stand alones. Has there been anyone who has been working directly on the car's ECU? Not the usual suspects ie Mine's, I am taking about some other tuner...

honestly the stock ECU will be dominated by EcuTek and Cobb. no real reason to go anything else due to the limited capabilties of the current crop of choices.

Next off will be stand alone ecu's. Motec, AEM and syvecs.

Motec already has alot of the development on the R35 done, i think they be writing more code for the M1 system, but it will be pretty good and offered soon this year. Syvecs will be the system to get and most likely the most affordable with what it includes (the sensors). The Motec system while great has only been tested at stock turbo, there is no doubt it will supply big hp (just like cobb, ecutek etc) but how it works with that power in the trans is whats its all about. Syvecs is already been tested and run at those high hp gtr's with more effecient transmission capabilities. HKS will be releasing the next version of the v-pro, but i dont think its as advanced as the syvecs nor the motec and costing alot. also the current v-pro needs the cobb or ecutek to get any more hp than the system offers stock from what i remember reading. greddy had some greddy labled system in there 35x (bensopra body kit), dunno if that will come to market or not and what it will include as of features.

AEM is unknown what capabilties it will offer for tcm integration. i have not heard of anything on the R35 front on this platform. Dunno any ETA either.

anyways, all these systems will make power. its the features, effeciencies, cost, software, intergration, logging, etc that will set each one apart.

All those are plug n play mostly aren't they? I am talking about the ECU itself, has anyone attenpt to mess with it directly?

like i said Cobb and ecutek will lead the best results in that area. plenty of Asain and some German tuners will modify the stock ecu but will never advance to that of say an ecutek. its just to advanced.
as for changing ignition, spark, fuel, bla bla bla just to make power... lots of people can attempt that and succeed.

The question I am asking has to do with the fact that the stock ECU keeps making adjustment to whatever tune the standalones or piggybacks may have made, which means that there is a constant need to be re-tuning. Let me hope that makes it a bit plainer then, go check the VX-ROM, along those lines...
