Ive used the hack on several friends cars with no problems, but they've all been civics. On my lude, Im using dsm 450's and an safc. when I hit boost for a while, it throws a cel code for the map. I was told that its since my settings are so positive(-10's), can I fix this by placing check valves? or will that throw off the hack settings?

 

I have a venom intank, not installed yet tho..but Ill try it out. But my question is..civics and integras run -35 to-40ish right? they're stock injectors are 240cc, preludes are 340ish cc... wouldnt -38 be kinda lean?

 

if your running 440cc...here is a roundabout estimate

340/440 = 77%

so therfore you would lean it around -33%

get it?

340/440 = 77%
340/550 = 61%

this should solve your cel light. You won't need check valves when you hack it

 

so on a civic(240cc) with dsm 450's, your calculations lead me to having to lean it out to -53?

240/450 = 53%

Im not that good at math, correct me where Im wrong
