I have the valet mode and knock CEL working on my UK car. Rom 93660005. Cheers Barry for the roms. Love the knock CEL, good work. I'll get a donation sent ASAP.

The NLTS doesn't work although I have a few other roms to try, just haven't had time to copy and paste all the tables over yet.

I am really looking forward to the Altmap patch for this ROM.

 

Hey Guys,

Just working on the last update to my ROM, quick question.

For the IX's out there would people prefer me to dump 1,2 and 3 timing maps in favour of just 2 timing map (one for low oct and one for high oct)

I already have done this for the altmap function, I'm talking about regular non-altmaps here!

 

I would think that going to 1 map on each side would most likely be the case when we go to interpolation. having 3 maps, then 1, would be difficult, wouldn't it? I think most people tune them all the same anyway. that's my vote.

 

I'm not sure i understand what maps are used, and at what time. So I don't think I have enough knowledge to say either way.

What I do is: during tuning I put all maps the same. Then, once tuning is done I put 1 and 3 back to normal.

I figure, if my car starts to get a little hot(or whatever the parameter for switching to those maps is) I'd like it to function properly. (I will be tracking my car this summer)

Again, I don't exactly know what each map is for, so I may just be paranoid. Any info that would help me make an educated decision would be... helpful.

 

whats the difference between 4.2 and 4.8?

is there a summary sheet somewhere?

if tephra is working on new tinkerings, will this be the 4.9?

what happened to 4.3>4.7?

 

The two additional maps are related to mivec timing. As mivec timing advances or retards the ecu interpolates between map 2 and either 1 or 3 depending on advance or retard of mivec timing, not sure which map is for advance and which is for retard. Elimitnating maps 1 and 3 would be the same effect as setting maps 1,2, and 3 to the same values.

 

Well, we added the addition of an ECU pinned input (which is a HUGE thing) and then have worked on ways to use the input for instant map switching with a switch or with a failsafe trigger(s) from a water/alcohol injection kit. Myself tried a few different versions for him (beta testing) while he got things working which made the version # increase each time.Then Tephra has recently added another goodie from MrFred which brings us to v4.8.....BUT NOW he's adding something else which is huge which will probably end up at v5.0 before its launched.

In the past 2 months, more features have been added than ever before for the stock ECU. Its gonna be freakin' sweet.

 

2 maps gets my vote. 1 high - 1 low Octane maps!

 

It would be nice if someone could quickly give us a feature list!

 

Tephra will be posting a full list very shortly when he debutes the new patch and its features.

 

<-- Highly anticipating map switching on the IX. Thanks for all of the hard work guys.

EDIT :: Just saw the previous post on wiring a switch for map selection on the IX. Great work guys. I'll probably jump on the bandwagon around 5.0.

Also, 2 timing maps should be fine since most of us tune all 3 sets of maps the same anyway.

 

2 maps works great for me.

Once boost map switching comes out I will be in heaven.

 

Heaven isn't too far away I bet.

 

Wasn't that a Warrant song?

Yes, boost map switching will be quite nice. Although, my race gas tune doesn't currently use any extra boost since I'm already running like 25 psi on the street.

 

LEAVE THE 3 MAPS THERE, that way when we figure out what the 3 do, you dont have to rewrite the rom, plus this was the car can function the way it was intetended.

Doesnt anyone know someone at mitsubishi and they can what why 3 maps?
