does it have to be a motec map? :?
If you have a read through this thread on Passionford there's some interesting stuff in it. It's abit long tho :?

here you go, very basic pulsar map.
x axis = rpm, y axis = load
ignition values are degrees in advance
fuel values are target lambda values
hope it helps,
Ross.

thanks ross. a few question's
1...what do you use for load axis?maf voltage? what increment is it in?
2...so you've set target lambda value's and the ecu change's the fuel point to set that lambda ratio? like quick lambda i suppose.
3..your map look fairly lean espcially at high load's?
4..do you have adjustment for cold start enrichment?
5..do you have to set max amd min inj pulse width?
6..can you set different inj duty cycle for different section's of the map?
7...what egt reading do you get?
8..does the fc show inj pulse width on the fuel map?
thanks zia

Do you want a copy of mine fella :?: , I can get rishi around to pull a copy out of my motor

rob that would great! :lol: does rishi have laptop with a floppy drive, mine doesn,t.
well having had it setup by tuner, i was apalled by the mpg.having bought wideband i found the a/f from cold to be 10.0 dropping to 9.8 between 2000-2500 how the tuner missed and did nothing begger's belief!!.so have decided to learn myself. the motec is all dos based and the software is quite archiac . have started to change and adjust the cold start acceleration and engine temp to see what a/f i get and with little playing have incrased a/f ratio 12.0. the first noticable benefit was the turbo spooled sooner and had positive pressure by 2500 even with large .87 exhaust housing :lol: . at the moment still got alot to learn, but since you don,t get logging as standard on the motec, have decide to upgrade to pro!.also the possibilty of going to map sensor is one option but would like to stick with z32 for the moment.

Hi Zia,
With the air and coolant corection maps you should not have to touch them as the are normaly very good from factory on most ecu's. If you are having problem with the idle or it is hard to start or genral running problem them look at the fuel scale for the injection system as if you have larger injectors it will be alot better to scale the map down to suit the injectors rather than to remap the fuel and ignition. This will also keep all the correction maps and throttle pump maps etc... all in good order.
Have found that the power fc maps are not to good for fueling referance but the ingnition ones are fine to use as a guild.

Mate. you save the map to the hard drive then load it or save it to what ever format you wish. You should have a directory for the maps that was created when you loaded the software.zia said:

mate what motec ecu have you got.
