ECU flashing
A while back [ before Utec ] There was alot of talk about flashing the timing in both the normal and agressive maps to the same timing . Did that work ? Was it a good idea ?
Im still using a piggy back EMS and since I added the W/M injection . Ive noticed that the ECU goes back and forth between the two maps . From the OBDII I see ....on WOT runs...Timing of 26 degree's [ normal map ] to 31 degree's [ agressive map ] I was thinking of having the ECU flashed so both are the same . IS IT STILL A GOOD IDEA ? flash to the normal timing ? or the agressive timing ?
Thanks !

I would go with a conservative tune on ALL maps, then if you wish to add timing you can do so with your piggy back, this way if the piggy back ever falls it will revert back to the OEM map which would be a "safe map"
This also helps your piggy back tuning be much more consistent and reliable.
Good luck!

the only problem I see doing it that way with the conservative timing maps is the SS box can only adjust timing every 500 rpms right? So wouldn't the timing map be kinda lumpy and not run quite as smoothly?
When I talked to AAM about a year ago, they said it isn't really recommended to use the same tune on multiple maps or that you wouldn't want it.
I think they said it was a case of there's a map and if the ECU detects knock it'll pull timing. If it detects you're really stomping it and want power, it'll try to add as much timing as it can up until knock occurs. But that you wouldn't want to force the default maps to be the same thing because then the ECU can't really compensate for knock or bad gas until it's too late - like it loses range or something.
I also talked to technosquare before that and here was something they emailed me back on Wed, 12 Apr 2006:
but then here's another email from them almost a year earlier on

and another email on a day later on Thu, 23 Jun 2005:
so there's a lot of conflicting things being said

3 maps are chosen by the quality of the gas mainly.
Current Nissan ECU sets the ignition timing by the calculation based on
MAF signal and injection pulse width.
So, we take that under consideration and re-map the timing correction
map as necessary.

Won't work. We tried.
If you would like to try a map with everything the same for timing, let me know

When I talked to both technosquare and AAM a long time ago, they said it isn't really possible to use the same tune on multiple maps or that you wouldn't want it.
I think they said it was a case of there's a map and if the ECU detects knock it'll pull timing. If it detects you're really stomping it and want power, it'll try to add as much timing as it can up until knock occurs. But that you wouldn't want to force the default maps to be the same thing because then the ECU can't really compensate for knock or bad gas until it's too late - like it loses range or something.
maybe they were talking about long and short trim maps or something?
anyway, that was about a year or so ago when I asked AAM

And in a boost , you will probably never go higher than 21 degree's of timing anyway . So you will always be retarding tiiming

The thing you have to realize is that you need the same tune and multiple maps to start a base calibration for your next map, the only reason you would want a different map at the same boost level is if you had a car that was running higher octane / more aggressive timing etc.
no one is talking about selecting different maps, but locking the ECU into using "one" map by overwriting the both the ECU's normal and aggressive maps with your final map so the ECU no longer switches from one map to the other with a mind of it's own
no one here is talking about running an additional map for more power

Hey Booger,
I am aware that you cannot add timing with the split second box, I was not aware that you were stilling using that unit, or I missed it in your post. I thought you would have upgraded to a EU, UTEC, or something of the sort
Good luck.

Im stubborn and refuse to change it till I abolutly have to and I can afford it . Plus every time a new EMS comes out it suddenly becomes the best yet and the last one was a piece of junk...lol THANKS Bill
Does any one know if the Utec has come out with a Windows based software to run it ? Or is it still the aftermarket application ?

i'm pretty sure you can have all three maps coded the same way so you're running just 1 map, and then using a piggyback to have X variable map settings..
is that what you're looking to do?
