- - can't boost more then 30psi ??? (https://www.evolutionm.net/forums/ecu-flash/555691-cant-boost-more-then-30psi.html)

can't boost more then 30psi ???

Hello,

I was mapping my car yesterday and I cant get my Evo 9 JDM GSR to go more then 30psi when I go over 30psi its like I hit a brick wall the ECU is cutting the power but only when I go over 30psi I am using ECU FLASH I have HKS EVC boost controller so I am not using the factory boost controller is there a setting in ECU FLASH of is it the MAP sensor ? My JDM map sensor is 3 bar could it be maxed out ??

I am hitting 374 Load with 29.8psi I am running AMS GT900X http://www.lancerregister.com/images/smilies/smile.gif

Hope some one can help me http://www.lancerregister.com/images...mitsu_logo.gif

You are hitting the 380 load limit point.
What is the ROM you are using?
Tephra or mrfred may have the address of the mod that doubles the limit.

My load is 374 but when it goes to over 30psi id does like a fuel cut I need to map this baby to 35psi I am using 109 octane sunoco. on lancer ragester they told me to set Boost delay timer from 1000 to 10000 and my map is set to 380 load so I also need to set it to 420 load :)

ROM 89980000

what do you think about what they told me ?:mitsu:

That sounds like you're hitting the boost cut limit...what's the max load you're seeing?
You need to raise the boost cut load.

in my ROM I have boot limit I dont see boost cut ? the boost limit is 319 and it does not go higher then that :confused: :crap:

My Max load so far is 376 but I can't go higher because of the fuel cut boost :(

While this isn't your problem, it would be a good idea to add this so that you have control over 380 load. So, get this done.

If you have your boost delay timer at 1000, then that's your problem. Either do the patch that enables your boost cust to go above 319 or move your timer to a number you won't hit, like 100000. You are hitting fuel cut because of this table.

As far as your map, you don't *need* to map out to 420 load. You can to get better control of fueling from your last load now to 420, but it isn't necessary. The ECU will use your last load column to account for fueling past that column.

thanks for all the info I will keep you posted on Monday I will tell you how much load I have with 35psi :) one thing I am using Sunoco 109 octane what would you guys recommend AFR ratio 11.8 or 11.4 at max RPM ?{thumbup}
