i need to figure out what kind of cut im getting. my car pulls hard as hell up to around 5600 then its either boost cut or fuel cut. im using a mbc. its turned down and im on around 20psi. i need to figure out how to post up my afr/timing maps so you guys can give me some advice. i tried to post them up but i cant figure out how to post them to the site. give me some help guys.

 

What do you have for the values in your boost limit and boost cut delay timer tables?

It sounds like you are simply hitting fuel cut because the values above are too low.

Your values are probably from the stock map.

 

3k 255
3.5k 255
4k 255
4.5k 255
5k 255
5.5k 255
6k 245
6.5k 235
7k 235
this is my boost limit table

the delay timer is 1000ms

 

i also have one more thing. i just want to make sure im correct on this but where you select the ecu i have efi selected. is that correct?? theres a few to choose from. ayc, abs, obdII, efi and some other

 

You are most likely hitting loads higher than you have posted for your boost limit table. Have you logged your 2-byte load? If not, log it and see if your loads are higher than what you are showing in your table above.

If you are, simply raise the load value to a number higher than the actual load your are hitting. In other words, just set the load where your want to have fuel cut. If you don't want any fuel cut ever, you can increase the load to 319 and/or the delay timer to a larger value, like 30 seconds, or 30000ms.

You probably are hitting fuel cut. With all those mods you have it's probably easy to reach that high load.

 

With my Evo Green even at 20psi I am hitting 280 2-byte load.

 

ok how do i log it in 2byte??

 

oh all the head is stock right now. i have another head that im building. i know that matters. im still on stock cams and all at the moment. im just tryin to see what i can achieve before i drop in the other head.
