mk3 Supra w/ fcd from hks
 

hello, i just got my 89 supra running, and i have straightened out almost all of my little bugs the only concern left un answered is why im getting a feeling of fuel cut, idk if it is forsure or if there is a chance of some tiype of limp mode, but all i can suspect is fuel cut,

i have a short list of most of my upgrades on my sig,

but in full throttle i seem to be hitting a brick wall and it is clearly cuttin fuel but its at about 3,500 rpm

i have the hks FCD, does anyone know what setting is the best for my 7mgte?

FCD is a HORRIBLE idea... ancient tech and way too much potential for damage. There is no magic number, it depends on your build and your tune.

How did you tune the fuel? Have you got a wideband installed? What's your AFR when it stumbles?

My money's on the engine running lean or fuel cut.
