You could probably run and drive on my map. Just change the required fuel amount in the engine constants to match your setup. It is verified to 18psi. If you want it, give me your email and I will send you my .msq file.

dohcrt i just read your logg really the only thing different your doing is running a 2.0 so theoreticaly i should be able to add 20% more fuel then what you have and go from their..... but since i also have 3 inch o2 and dp i mite need more... but your map should be a great start....... what code is it for though.. i got a older version then what out know.

I think its 029y4. If you don't have the latest firmware, you should upgrade.

Setting the constants correctly will increase the fuel for you. You will be better off setting the boost low (waste gate minimum) before you try it out. Torque is going to come earlier in the RPM for you engine than it does mine. You will notice that my VE table peaks around 4500 RPM. This is where my engine makes peak torque. Since yours will peak earlier, you will eventually have to change where the table peaks to compensate.

The spark table is very conservative so you shouldn't have to worry about having too much spark. Get the fuel worked out and then play with spark.

I have most of the enrichments tuned very well so it shouldn't be too hard to drive without changes.

I sent the msq file to your email.

thanks. yeah i got the 029y4. i loaded it to megatune but says their are 26 warnings.. possible cause it wasnt hook to a unit? looks good though think i can use it even though i have a 2.5 bar map?

You will have to change some settings in the MT configurator. Be sure to setup for a 2.5 bar MAP sensor. A lot of the warnings are probably being caused by the fact that our hardware is different. You may want to create your own msq and just use my tables and enrichments.

what do you mean by different. i just need to know what version megatune your using.

2.25 p1

Different as in my MAP sensor is 3 bar and yours is 2.5 bar. Some outputs are different on the Super420A than a regular MS1. Also, I am using IGBT's instead of VB921's. You're going to have to lower the running dwell time if you are using VB921's.

ok.. ill have to look when i get it all loaded up....i looked it over and from what i understand their is really no difference between the 2 version just a fix on some things..... i notice your spark table goes to 300 kpa and your ve goes to 249 if i change the map i wont have to chande that will i?

If you have it configured for the correct MAP sensor (2.5bar in your case), you should get an error for any setting over 250kpa. Change the highest kpa bin in the spark table to 250kpa and move the whole table up one line accordingly.

the highest setting in spark is 249kpa then the one above that is 44.. also dwell time is lowered to like 1.5 or somthing like that?

MT probably got confused and changed it to 44 for some reason. Dwell time with VB921's should be around 4.0ms. Cranking dwell is going to be high so don't worry about it. Be sure spark output inverted is set to YES in spark settings.

ok cranking dwell is 7.o and running dwell i lowered to 4.0ms that sounds right ? and the spark invert is set to yes.....
