PTUNING: Haltech Standalone ECU (Screen Shots pg. 5).....
#121
aem can still get you oem style drivability if you tune it right.. i think its just the ac and idle issue that i've heard of the aem. Also that thought that aem for power and hydra for drivability is a funny logic, obviously doesnt know much about standalones. This haltech is great though, i wonder what the 1500 price comes with

In all honesty, you will probably not find too many tuners using individual EGT inputs on an inline-four cylinder set-up, as this would probably be overkill. On a side note, the Haltech unit can also accept a fuel pressure input (among many, many other available inputs) - nice safety feature.
The software has many available outputs available to use as a WMI injection channel. It can trigger with both rpm and boost and also air temp changes, etc.

The Haltech ECU does have the capability to adjust fuel trim on a per cylinder basis. It also has the capability to accept a single EGT input and provide fuel trim based on EGT temps.

I think it would be an overkill too to have an EGT input for each cylinder and have some fuel/spark trims to it.. One input that trims fuel/spark should be enough, you can put 4 egt bungs but use it one at a time while tuning individually. EGTs on each cylinder shouldnt vary a lot, if it does I would just use 4 wideband bung for individual cylinder afrs.

^ if only i had a friend that was a tuner i would tune my own car - there just is no way im trusting myself on an engine when that engine takes me to work. i know i could learn it ....just im not testing w/ my car - hehe

True, but the beast I am building I want every cylinder perfect power balance and just having widebands will not do this. Widebands only tell AFR. The only way to truly tell how each cylinder is ruining would be with both wideband and egt.

^^ nothing wrong being a perfectionist, if money isnt an issue then individual ftw. I dont think it can trim egt on all 4 cylinders at the same time though, I have yet to set that on 4 bangers.. but you can still tune individually doing one cylinder at a time.
Surely that would be an interesting build, usually I only see those on 6 to 12 cylinders where VE is affected by many factors like staggered turbo setup, turbo location, different intake manifold design, different AITs, pipe bends, downpipe design etc.

i would assume it will have, its a common feature for standalones. What it does is that it has a table where you want to what your afrs you want, usually in a rpm vs load map. You turn on the autotune and it will reduce or add fuel based on your set afrs, it uses your closed loop system.

The Haltech software allows you tune using VE tables or standard load-based tuning using injection time (common tuning method).
BTW, all current and future software/firmware updates are available to the tuner or end-user free of charge.

It also features a user configurable O2 feedback map for closed loop fuel control. This operates in the same way as the factory ECU would in that it helps to improve fuel economy during low load conditions to allow for optimum fuel economy when cruising.

For those that are waiting for the release of the Haltech PnP Standalone ECU, we are just waiting for the final ETA on the completion of the PnP Harness. With the overwhelming requests for this new ECU, we hope that it will be soon.
We will post the pre-order pricing and final product pricing as soon as we get confirmation on the availability date of the harnesses. We will also be releasing pricing on the available PnP Haltech WB controller and sensor too.
As of right now, the unit should still meet the sub $1500 price target that we originally mentioned.
