UTEC Delta: help us all learn

[CHAOS]

ok so ive been hearing about this new fangled version of the turbo xs UTEC called the delta... what changes have they made... how can we all benefit from it... is this now the best way to go? any info would be awesome.

[ej20wrx123]

I thought the delta was the same thing as the newest version of the utec except that it can be used with any car if you have the right harness. The UTEC w/ SD=greatness

[TROLL]

if anyone knows the differences please list them, cause i'm not sure myself.

Turbo XS no longer offers their old version of the UTEC, now being sold is the Delta.



HopUp Racing

"TurboXS Delta UTEC Subaru WRX 02-06

Turboxs no longer sells the older "Utec'... They now sell the Utec Delta. In the past you had to purchase a utec that was Car specific, The STI utec, WRX utec, 350z Utec, and the EVO utec where not interchangable. Now, with the utec Delta you buy one box that will work with all cars. You simply need the correct plug in harness to match the Delta to the specific car.

Standard features include: -Plug-&-Play -No cutting, splicing or additional sensors required -20 minute, do-it-yourself installation

-End-user programmable via PC,PDA with HyperTerminal, and our Game Boy and Smart Cable -Fine tune the maps for your exact setup -Pre-programmed base maps get you started quickly and safely -Base maps for our Staged upgrade packages -Five (5) maps plus "stock mode' selectable with a flick of the switch -Create custom maps for street gas, race gas, nitrous, or whatever -No need to lug around a laptop just to switch between your program -Optional remote swtich

Fuel, ignition timing, and boost are programmable in 250rpm increments up to 9000rpm over 10 load sites

Complete ignition timing control

Fuel control Controlled via MAF sensor signal offset Tune stock and larger than stock injector

Load reference MAP (manifold pressure)

Closed loop boost control programmable via Throttle Position and RPM

Knock control Automatically retards timing when the knock is detected safeguarding against engine damage Adjustable knock threshold, timing correction, and duration

On board data logging Built in programmable solenoid controller Control Nitrous, Water Injection, Intercooler Sprayer etc.

Drag racing launch control (secondary rev limit used during launch)

Note: Utec and harness included for the Subaru WRX."

so what confuses me... is why get ecutek over something like this? switchable maps is awesome.

[D Money]

Andy said Ecutek should have switchable maps by the end of the month. They have been working on it for a while now.

[TROLL]

you need to understand the basic differences between a reflashed ecu and a piggyback system... the biggest difference in my eyes is adaptability for changing conditions, which can be good and bad.
a factory reflashed ecu will be able to actively adapt to changes in weather, fuel, etc and adjust in one direction or another to make suitable adjustments. this is great for a low maintenence car that you dont need a lot of gauges for and dont have to be actively logging to a laptop to make sure things are still good for changing weather, fuel, etc.
a piggyback like the utec will not deviate from the settings you program it with. this can be good or bad because you set it up and you know thats exactly how its going to run every time, but what if you get a bad tank of gas or it gets hotter or colder and that changes the air delivery to the motor?

that would be the way to go then IMO

[ej20wrx123]

I've been hereing about Ecutek and switchable maps for awile (like years and they would only have 2 maps).....and i doubt ecutek will ever have SD which is the big reason people go for the utec.

I think that the utec can change according to the weather/temp if tuned for it....which very few tuners do.

They do have limited map switching abilites, and have had it for a while. Although its not a complete map switch(fuel,ign,boost) you can switch between boost maps.

You are correct about hearing about the map switching for years. Just look on there forum and you will see that it is a long awaited product. There developement of the user reflash/map switch software has been delayed many times for another project. Hmmm I wonder what that project could be?

Up until version 5.8 there were no usefull corrections for temp changes. If you wanted to account for temp changes in previous versions, you would have to tune seperate maps and fill the map slots with those different maps. Now in version 5.8 the temp corrections are very good and help out a great deal with driveabllity and safety.

The Delta is just the evolution of the Utec. Dont get too caught up in map switching abilites. Its really a novelty that wears off, unless you run racegas often and require map switching.

My recommendation is run a Utec over an EcuTek flash. That combo is more powerful than most standalones out there. You get the benifits of the stock ecu, and the benifits of a parallel system that has all kinds of goodies, like launch control, shift light outputs, spare solenoid outputs datalogging ect.

When it comes to the debate about engine management options, it breaks down somewhat like this:

Easiest: Stock ECU reflash
examples: ECUTek / Accessport / et all

Benefits: simple 'set and forget' setup. Maintains all functionality of stock ecu system including knock correction, emmisions compliance, check engine light/OBDII

Downfalls: limited or no ability to change maps (AP allows swapping of maps on the fly), limited amount of writes to ECU before potential failuer (>100), limited depth of tuning (less data points), inability to drive ancilary devices easily or with adequate safeguards (Nitrous/water\alk injection), reliance on factory MAF sensor

Cost: cheapest

--------------------------------------------------------

Medium: Piggy back ECU system
examples: UTEC/Delta

Benefits: Expanded user controlable paramaters, ability to drive ancilary devices with safeguards, advanced funtionality (launch control, flat foot shifting), ability to run off MAP sensor eliminating need for MAF concerns, Easily selectable multiple maps, retains OBDII/CEL, Emissions compliant

Downfalls: relies on factory ECU for many functions, cost on same leval as some stand alone systems without the same leval of control, limited ability to adapt to extensive modifications (IE: TGV removal), requires more user interaction to adapt to environmental changes.

Cost: Medium

---------------------------------------------------------

Hardest: Full stand alone ECU
examples: Element Hydra, MoTec, Audtronic

Benefits: Full control of all ECU functionality, expanded/larger mapping area allows for more fine detail, Auto tune functionality allows for factory ECU like real time changes, ability to drive accessories with full functionality and safeguards (ex. hydramist), ability to drive non-standard/non-factory injectors directly from ECU, ability to adapt to extensive modifications, ability to run a fully MAP based system, advanced user options (launch controll, antilag, launch control, etc...)

Downfalls: highest reliance upon tuners or community to establish a running vehicle, cost/cost of tuning, lack of ODBII/Emissions compliance

cost: highest

i'm sticking with the route of ecutek and will wait to do the map switching when they release their version of it.

Why not go with a custom tune and an access port?

-Cliff

[ej20wrx123]

why not go with the delta and a tune. Unless i'am missing something its does everything the Ecuteck/AP can do, plus much more. Whats the point of going with a ecuteck or ap over the delta??

Simplicity. If he simply wants a flash or simple tune, then the Delta offers no benefit to him. Getting the access port simply gives him the option of swapping maps on his own if for instance he travels across the midwest and doesn't have 93 available, he can swap down to a 91 octane map, plus it will read and clear CEL codes. It does this at a cost that is very similar to an ECUtec flash.

Really, he could get the cable and software from OpenECU, and do it for much cheaper, as long as his tuner is comfortable with the software.

-Cliff

[ej20wrx123]

I'am not talking about people that just want a quick flash or a simple tune. I'am talking about people that mod their car and pay big bucks to get a pro to tune it. I dont see any advantage of the ecuteck/ap over the delta other then a couple hundred dollors(maybe), or if you dont have a local tuner that does delta.

openecu=ecuteck......so imo its not as good as the delta

[HuffRex]

I love the simplicity of it. Andy has tuned my car in the past and continues to do it today. I have trust in who tunes my car and hasn't given me a reason to go another route. With the map switching capabilities coming out...all i will have to do is upgrade my mbc to a turbo xs dual stage and install the appropriate software on my laptop and i will be set to just easily switch my map from 93 oct. to c16. I love the simplicity of it. I don't need functions out the ass.
