On a stock motor their isn't really any reason not to run one, helps if you want to run an otr intake or tight spaces in an engine conversion

Hey guys been playing around on pcm hammer with my ls1 adventura, got it runni much better fueling is on point now and changed a bit in the trans setup but haven't quite figured out how to setup to go mafless though, has anyone had any luck/how has it been done so far? Any input would be greatly app...

My laptop doesn't want to play the internet game so I can't post anything useful at the moment..
The cam is a csbr 523 from come racing, the specs come up when googled

Overlap is, in degrees from exh closing @-1.8atdc to intake opening @4btdc so 2.2degrees? It sits steadyish around 14.6-7 but as soon as it enters closed loop it starts pulling a heap of fuel What's odd is the narrow band o2 is showing that it's running lean aswell, but it's still pulling fuel.. hav...

It's 222* intake 232 exhaust 113 lobe separation and if I remember around 2 degrees of overlap
Surely a "little" reversion can't spike the fuel trims to Max? It's fairly steady around 14.7 until stft takes up to its 20% Max fuel reduction

Hey have a bit of an odd issue, just put a cam and ported heads on my l67 vy, and now at idle and only at idle it sits for a moment at 14.5-14.7 then the fuel trims start leaning it right out past 16-17afr and I cant figure out why.. currently disabled closed loop till above 1200rpm to stop it happe...

The tune is one I've made up with a fair bit stolen from a l67 tune, I can post it up if it helps anyone. I'm glad to hear it could just be mechanical noise, I had been pulling timing with no noticeable result's and was starting to worry, I'll look into burst knock settings and perhaps some decent k...

Hi guys been playing with my vy l67 , seems im detecting knock at almost every fast gear change (manual) and when I blip the throttle but not under load or high rpm, could this just be mechanical noise? Doesn't (seem) to knock under load or high rpm , should I just pull more timing till it stops or ...

Yes, I copied everything I could from the s/c tunes I could find and made a few adjustments based on my logs, I've got it idling and moving around ok, drops to 12ish a/f on pe, running a lot less spark than standard though, I'm also going off the end of the scale in inj multiplier vs mgc vs rpm, the...

Ah yeah I'm running a 4.2 s/c stroker on a vy flash pcm with the ones enhanced na vy tune, I changed the injector scaler to suit the l67 injectors i have until I get some larger ones, i have a wideband gauge and also have a reading through the ecu and it's running ok, a bit rich (I'm still learning)...
