yep. 75/25 mix, 7gph nozzle, cobalt addiction h/e and 2 step colder plugs.

 

94 octane out of the pump is amusing.

if you can do back to back runs and have zero knock at the afr and timing level. leave it be.

 

how the **** did you get one of my maps?

this, i want to know.


i keep my sharing to people whom are of the educated lot, you have proven that you are not to that level yet.

the "harm" i see in you useing OTHER people maps is simple, your profiting, and proliferating off other peoples work. all while not understanding why things are done specific ways.

and that, tool, is my biggest pet-peeve.



also to the one who asked, MBT and such are all derived from engine VE vs RPM.

peak torque can be shifted around with advance, however much past 5600 or so and the cam falls of hard enough that you have to kill cylinder fill with fuel in order to support it. but the later that peak hits, the higher your power curve will climb, and to top it all off, every thing becomes more linear as the math for horse power starts to work in your favor. post 5252.

thus your curve should become a semi-horse shoe, as you MUST fallow cyl pressure for max results. the only way to get a hold of thus mark is time and effort.



this is basic stuff here people, there are no tricks or snazzy formulas.

 

Thank you!!! It's the basic stuff that I'm still learning

Finally an answer. I'm gonna go celebrate.

 

go find it on your car.

cyl airmass can help point you in the direction

 

ok well i got my car re-tuned the other day to adjust the afr that my header/dp/exhaust messed around with. Also my trim was at 25% so we fixed that. im now at 11.9afr and 25* of timing. Still havent seen knock and iat2 got to 149* after 3 pulls on the highway in 27*C weather. Man that TVS just wants to keep making power...lol

 

mine as well... which is why i cant wait to put my new valve springs in

 

im thinking that same thing...get valve springs so i can put my rev limit up to 7500rpm

 

a few people would argue that you can run that high with stock valves

 

whether people say u can or cant. I'm not risking it. I'm pretty sure im pushing the limts of my engine as is...im not going to take any more chances in blowing it up. 11.9AFR 25* timing, 20psi boost 7200rpm rev limit is good enough for me on stock internals.

 

you can, if you have a low mile engine. you would be surprised at what the stock engine can take

 

i run 7,400 rpm's on stock exhaust and brought it up to 7,400 many times.

 

mine is at 7500 with stock springs lol... prolly not the best idea, but ive got another engine ready to go in my car

 

i used to run my car to 7,400rpm

 

What is your meth/water ratio? What size nozzle are your using?

Useta huh?

 

well its back to stock now.

 

i might try to see what 7400 gets me... when i change my downpipe. it could be cool to see an extra couple of ponies

 

Is this a good timing table for a LSJ with a 2.9" pulley and 42s?

 

I would smooth that out. Big spikes like going from 7degrees to 19degrees isn't necessarily "bad" but is harder on the vehicle from what I was taught at least. With the 2.9 and 42lbers I would be more worried about idc's and pw instead of timing personally. Are you using any timing multipliers/adders? What is the total timing the car is seeing on a wot pull?

 

This is not my tune. Its a "custom" tune I pulled off a local car.

There is IAT adders. But they really don't come into play until the car sees 140 IAT. So it has to be on fire.



There are ETC adders that start at 140 and lower. And ETC subractors that start at 248 and higher. Again. They should never be touched once the car is warmed up.

 

if you're going for torque that's peachy. sort of.

 

75/25 mix with a 7gph nozzle. Did dyno tonight. 4th gear pull...281hp 249trq @ 7000rpm. Abit low for some reason. But oh well, most likely selling the cobalt in a few weeks to buy a 370z

 

drop down in nozzle sizes. 5gph is enough

 

I'm circuit driving my 2.2 OE valves which are weaker to 8200 rpm at each trackday, with stiffer springs.
Still alive, approx 8000 km and 1000+ km on track with a 12.8:1 AFR.
(In truth, I had a set of SiValves. Intakes are in the engine, but exhausts were crappy and out of tolerances so stuck with OE ones for exhausts...)
