ecutec reflash vs utec???
what are the advantages of the UTEC as far as tuning capabilities over the ecutek reflash or vice versa... I know that you can switch maps but im just curious is there more the tuner can do besides that

UTEC - switchable maps with multiple tunes. Utec tricks the ecu and doesnt adjust it directly. It tends to always have some sort of knock issue, it doesnt adjust to the atmosphere that well.
ECUtek - one map, adjusts a lot better to temperature, the power curve is much more smooth, ecutek can adjust AVCS and is a lot more indepth. i would get an ecutek... im on ecuflash right now, its almost the same thing and i love it. i used to have utec and i hated it. or you can have ecutek flash, with utec on top... |

or you can go opensource and run open ECU and not waste a ton of money.
Truthfully running OpenECU + UTEC is the best combo |

for the 02-03 ecu ecutek has 2 boost map option.
ecu af423... but if your planning on using more than 2 maps often then opnecu + utec would be easier. |

There have been a couple of persons who have said that ECUTEK is expensive and the truth is.....it is, this is not because I'm overcharging either, the cost of the license that I will need for each new car is expensive. But lets put things into perspective, is it worth it? What do you think?
These are some areas you stand to gain using ECUTEK: 1. No Boost Controller is needed (can still be used however), ECU controls Boost (the Average EBC will cost about US$ 300 + shipping and duty) 2. On JDM cars with the 180kmh limiter....No Speed Cut Lifter is needed (Cost of Lifters avg US$ 200 + s & d) 3. No Boost Cut Defenders or other Boost Cut Devices are needed (Cost of these avg: US$ 150 + s & d) 4. No Fuel Computer is needed (Cost of these avg US$ 300 + s & d) Figures speak for themself... Additionally there is: 1. Increased fuel efficiency (in excess of 20% more mileage per tank) 2. Increased overall performance with significant low down gains 3. Increased engine safety on our low octane gas, our poor gas quality has been known to cause major damage to turbo charged engines (detonation and engine knock removed without any loss in power). One should also know that with the factory ECU still in charge of the car, it will be able to switch into limp mode (a mode designed to protect the engine), cut boost etc to protect the engine if for example: 1. You purchased bad gas (unknown to you of course, can you imagine if your boost controller is still at maximum boost on this bad gas?) 2. Boost control mechanisms failed and car accidentally is overboosted (you can customize your boost cut level to suit your modifications rather than have none at all) 3. A Critical Sensor Fails The ECU on these cars are designed to learn and adjust to varying conditions (temperture, gas octane, altitude etc etc), this learning feature helps the ECU to automatically adjust parameters within the ECU to firstly PROTECT the engine, secondly to extract the best possible performance given the parameters. These features are not available using the standard piggy backs currently available on the market. Some aftermarket ECU's will offer similar features (not to the extent of the factory ECU however), but the average aftermarket ECU cost more than ECUTEK and are more geared towards performance and you will lose some of the Factory features with such a computer. Aftermarket ECU's will be able to provide you with some additional features (eg. Anti-lagging) which for the average street driver is not necessary. In any event, the ECU's that provide additional features cost even more than the standard aftermarket ECU's. So, in summary, I think ECUTEK offers good value for money, and best of all, you will have support for it locally and a MONEY BACK GAURANTEE and excellent after sales service!! |

Also it will allow full tuning for RACE & PUMP gas on a single car, so drive it to the track, race it on a race map, drive back home with just the press of a button.
This ROM can be used on any Spec C from 03-06. It should also work with just about any JDM Impreza with VVT and no TGVs (STD WRX can have the TGV's removed so this map can be used). Please read through the feature list below and see if you can come up with any other features that could be realistically added. btw, I am not after suggestions of what ECUs to add Map Switch features to, nor do I need reminding that you'd like to live tune everything! This is specifically Spec C map switching features and small code tweaks only. The features so far... # Dual Base Ignition # Dual Ignition Correction # Dual Lo Det Fuel # Dual Hi Det Fuel # Dual VVT # Dual Desired Boost # Dual, per gear Initial Wastegate Duty (10 Maps) # Dual, per gear Max Wastegate Duty (10 Maps) # Dual cruise AFR settings. e.g. 14.7:1 & 15.4:1 # Per gear proportional turbo dynamics (5 Maps) # Per gear positive & negative integral turbo dynamics (10 Maps) # Rev Limit / Launch control ignition retard. # Dual Speed Limiter Maps The per gear stuff allowa you fine control of the boost control in each gear, so you can run agressive wastegate duties in say 1st gear from low RPMs, whilst in 5/6th gear the duty needs dropping at a lower rpm because of the increased load. You get 5 maps because you get 1st, 2nd, 3rd, 4th and then 5th&6th are combined. EXCLUSIVE ECUTEK MAP |

first the map is only as good as the tuner
second the open software does all that too putting a utec on top of that adds even more features its far more important to have an EM solution that your tuner is comfortable and confidant with than what every one else thinks |

At the end of the day, it also comes down to a matter of choice. I love the ECUTec.
But then again, I am just now educating myself of the others so i can't help but to give a biased opinion |

Open ECU allows editing of ALL the tables and maps in the stock ECU ROM. I am the first to admit that I am not all that familiar with ECUtec, but I cannot see how a refresh can do any more than Open ECU. My 2 cents.
The UTEC has some features, that to my best knowledge are not available through reflashes: launch control/flat-foot shifting, solenoid control, map-switch on the fly (with the remote switch), Speed Density tuning, etc. |

No tuning software, commercial or open source, allows you to edit ALL the tables on the stock ecu. The DBW cars (32bit ecus) have between 500-800 2d and 3d tables and well over 1000 1d parameters. Reverse engineering these roms isn't an easy task and even the commercial guys that have been working on it for years don't have it all figured out.
