Megasquirt Support Forum (MSEXTRA)

Hey Forum i just upgraded to MS3X Assembled 3.0V-3.57V, Tuner Studio Ultra v3.0.28 and are having some issues, timing is set at 10 deg for ignition, but for some reason i can rev past 1600 rpm

set-up is as:

1jzgte Non VVTI, stock internals
1000 cc injectors - sequential
Quantum 340lph fuel pump
Single Turbo 6262 T3
LS2 LQ9 coils - sequential
R154 gearbox with spec 3 stage 6 puck clutch
LSD Rear Diff
HKS boost controller
Spartan2 Lambda O2 controller
using MS3X internal MAP
Engine loop have all new wires and clips to all sensors, injectors.

i have attached my current msq and data log any help be appreciated

No run log (MSL) there, add it. Will it "not go over 1600 rpm" under load, or free-revving?

Then something is very, very wrong here. I have found that if an engine will fire and run at all, it will go well past 1600 rpm.

So, back to basics:

Have you checked spark advance on all cylinders?

Run it on one cylinder at a time to see if all are firing and seem to try to put out the same power?

Checked valve timing?

Checked compression?

When it hits 1600 is there any definite misfiring, any cloud of smoke from the exhaust?

PS: be sure to get us that MSL log...

Defiantly check timing. My 12 tooth 2jz and my buddy's 1.5j have a 5* offset to get timing correct, and that's really not adjustable unless you have your cam gears way off

Its fixed, cam was picking up noise and adjusted cam pots
