Anyone done a wrx 2010 ecu upgrade to haltech elite 2500? Anything to watch out for or just plug an play then tune.

Yeah they come with the ecu and PnP now days, Anyone had any time around these ecu's ? Are they as good as they say?
I dont mind the cost so thats not a problem. Looking for a powerful track day tuning ecu for my kids to step into when 18 with a highly tuned lanch control system to help them and by then i reckon a gold block will be in , where I'm thinking only closed loop map tuning and every senors know to man on it to protect the investment.
Might be over kill so im asking u guys if i should just go 2500 elite straight up , I got the cash too.

P.S want to make it a 11 second or faster by 2021

yes but isn't the IAT sensor in the MAF on a stock car? if so its pointless for SD and pretty sure they don't do knock control like the stock ecu which is very tunable at a fraction of the price nowadays????

If the factory MAF is removed , an IAT can be installed. It's supplied.
Manifold absolute pressure is a sensor to measure vacuum (standard install)
If you decide that you want to make way more horsepower than your car was ever intended for, then MAF just isn’t going to cut it. MAF’s quickly become bottlenecks in your air intake system because they can only measure “X” air at once. If your engine needs more than “X” amount of air, then your MAF freaks out causing your engine to run lean.
So there saying run both if not all 3 senors. Think 2 is enough thou (That info didnt come from haltech)

The ecu has the ability to have a 2nd knock sensor and monitor each bank on V8, maybe both sides of boxer to make better detection. Unsure of how powerful an easy to use as there are only Haltech youtube vids and information without any personal stories to read about. If i do this i will be recording the process for others to follow. Maybe i watch too much MCM but this looks easy just cant find anyone thats done it and shared there story.

I dont even know how much of the cars electronics i will lose. Cruise , dash etc. Going to spend some time on the phone with them today but as good sales person will tell u "there product us the best" .

Got to buy a $300 crimp tool for 2 wires. I know that.

Had a chat to Haltech today and only lose the cruise control until they fix in up coming firmware updates. So im going ahead and the project starts late feb with ecu ,better boost control, Intercooler and sports down pipe 3"+ cat with standard back end cause i dont want a loud system until it has the balls to backup the sound with power (stage 1 to learn how the ecu works and the tuning process myself after 1st basemap is made on dyno).
I will do a decent vid and bang it up after this and with any luck i can find a good tuner over east melbourne and have a nice dyno after chart with a clean power curve . No before chart, we have all seen them before.

Jobs done, 1st time installing ecu and working on forced induction engine. Plenty of stuff to mod and rip out during the job but 8days and it was going again. The elite 2500 is great. Base map tweaked so far and its pretty good tune,( not prefect by any means but close enough for now). The VE tune is going nice and wideband is keeping close to lambda or just under so after i play around a bit with 98ron i will bite the bullet and fill up on e85 an see if i can get it driving ok. Plan to dyno tune later but I'm more keen to see how user friendly the haltech stuff is for the average joe .

Ok so here is a vid of what I've done. Enjoy

More to come if people would like to see how i did stuff, over 120gig of vids including road tuning..... too much to edit for no reason,
