Ok is currently at 18 with no knock. It is cammed aswell.

Just wondering what would be a safe maximum wide open throttle timing on a forged supercharged L98 6ltr? On normal 98 fuel and about 12-13psi.

Not sure on the power as it maxes out the 250kmh on the roller dyno, pretty much just wanted to get afr right. It's a burnout car so has powerglide and 3:0 diff gears.

Iats were around 45degrees and it was a 32degree day. Yep on 98 octane fuel.

Ok my dyno reads down to 4.4afr with the alcohol selected.
I've got it tuned at around .76 lambda and 34 degrees timing with 1000cc injectors at about 60% duty cycle.

It made 552rwhp on 10.5-11psi boost.

It ended up being a issue with the wiring in the harness and run a few more earths from harness to engine to body and now all works fine and all tuned well.

Everything is what comes with the Magnuson charger from the Australian dealer. Start up tune, injector data everything. It's a stock ls3 with no can and just full exhaust, headers and twin 3" system.

In tail pipe, same spot as every car is done.

Yeh 10:1 is rich but The 10:1 in that log is all tuned properly now and not that rich. That was when it still had the start up tune in it but it's the only log I saved. But it still has that same...

It used to be e85 with the 8/71 on it and it was never ending problems as the fuel always had dirt or water in it from the bowser and now isn't available anymore, and also was always inconsistent....

I tried another car on the dyno after this that is tuned and wideband read fine, put this car back on and it reads lean straight away at wot.

It is a burnout car, Only reason I wanna run meth is to keep it cool, it's a big cammed ls1 5.7ltr with bit more compression. Engine usually has an 8/71 blower on it with mechanical injection but...

ok no worries and then it'll read with my dyno dynamics software and hptuners?

fuel pressure stays consistent at 60psi and injectors are what comes with the kit from the Australian magnuson dealer and they've never had this problem and injectors aren't maxing out.. I also tried...

ok I thought could just do that, then just up the ve table to suit? do I need a wideband that reads methanol or the normal one will work?

have you done it before?

can standard ecu be used to tune an n/a ls1 on methanol?

hi, i have a magnuson 2300 superchargerd ls3 (holden ve ls3 clubsport auto) at 10psi with 60lb injectors im trying to tune but goes extremely lean at wide open throttle, ive tuned everywhere else ok....

I'm having the same issue on my ls1 that I just put a victor jnr and 4 barrell throttle body, also has a 233/233 106lsa cam. Sometimes idles perfect and drops back to idle when slowing down then...
