Ok, Im kinda new to the ecu's and have done a search but couldnt find the answer. I was wondering if there was an ecu that would allow you to dyno tune different boost and fuel settings, then you would be able to LOAD the settings from a laptop whenever you choose. Do you kinda know what im talking about??

 

A Standalone Engine Management System (SEMS) will allow you to do just that..you can hook up a laptop to see what the various settings are and as you dyno'ing or shortly before and after, you can fine tune different things. The SEMS' allow great control over the entire system. These guys usually run in the $1500 price range.

The Apexi PowerFC is another option..not as full blown as the SEMS', but in most cases more than enough control to do your tuning. This will run about $1100 or so with the Commander, I believe..

The other option is a new ECU from Pettit, M2, etc., that is tuned pretty much to the mods you have when you get the ECU..so change the mods, you might have to chance the ECU..but you lose the fine tunability that you get with the other 2 options...

 

I thought i had heard that the Haltech allowed you to load in different settings as far as fuel, ignition, and boost?

 

The Haltech allows you to run up to 16mS of fuel injector pulsewidth at any one time.&nbsp The Haltech allows you to run up to 50&#176 of advance at any one time.&nbsp Boost control on the Haltech is pretty tricky, and I don't recommend using it myself; I'm a more esoteric type of person so I would recommend a boost controller for that function.&nbsp The Haltech can read boost up to it's limitation of it's boost sensor; a 3 bar MAP sensor is available which will allow the Haltech to monitor up to ~30psi of boost.

The Wolf3D 4.0 has integral rpm-based boost control, and it has memory cartridges (like a Sony Playstation) in which you can load a new map in seconds. Each cartridge can contain a different map, and the EMS keeps one map in memory. The other EMS products on the market can also load different maps within seconds, but a laptop computer is required for the loading process, and some of them do not have boost control.

Is the 4.0 going to be able to do a trailing split on a 3 rotor?

 

Absolutely not. However, the 4.0 does allow for rpm-based split on a 2-rotor now, rather than the fixed split of the 3.x.

 

Does the v4.0 have the security feature like the v3.xx?

 

Ahh, that would mean more work.

 

As far as I can tell, the security and datalogging features were dropped from the 4.0. I asked my local Wolf dealer about this, and he will be checking into it later this week.

Yeah, the 4.0 requires much more work due to the greater resolution and additional features. Hand controller tuning is rapidly becoming outdated, as there is just too much to tune now. You can still tweak the tuning with the hand controller, but it is no longer practical to do all your Wolf tuning without a laptop. Also, a lot of the Wolf 4.0 advanced features are only available through the software. I guess it's all for the better, though.

 

Can you do real-time tuning with the laptop?

 

The earliest versions of the V4.0 doesn't have the security feature, but when you upgrade to V4.5 or whatever it is up to now it will have it.

 

Yes, and it has on-screen gauges and readouts.

 

Thanks for the answer.

 

Haltech's E6K will very soon get an update to allow two maps to be stored on board and dashboard selected via a switch, even while you are driving. Current models can be easily upgraded and any dealer should be able to do it once it it released. It should not be too long off now, it just needs some small bug sorting.
A newer model they are working on will definitely support both 3 and 4 rotors ... IN FULL.

 

For security with any aftermarket ECU, simply take it with you if you are parking somewhere that theft is possible. The chances of a car thief not only having the same ECU as you, but also to have it loaded with a map that will run your car is quite slim. Taking it with you is less of an inconvenience than a long walk to the police station is.

 

Yo HITman, I can't wait to hear about the complete performance package this new ECU will have when you install it in full , and have it running in your NOT-20B Rx7 .... Keep us posted ...
