Need help on tuning my engine

[jimmyloh]

too much toe in brush off the speed, I own a sinyih before and I would said that,it may be a tawain made engine but it is pretty lasting even you leaned it down more than it should.

anyway if you are really into racing, dont really go and bother about toe in toe out, ackerman angles, camber, shock oil config........ blah blah blah. unless you really want to tune your car to the track condition.

general setting would be something like that
1. not more than 1 degree toe in/out on the front depending what is your driving style
2. Do not toe out on the rear, average 1-3 degree toe in
3. 2 degree negative on the front 1 degree negative camber on the rear
4. if you like to jump high and far, stand up your shock, if you like to play traction incline your shock
5. diff oil setting will be somewhere front 5k center 7k rear 1k
6.forget about roll centre.

make sure that you set your TX EPA correctly,if not it will either screw your servo and carb or the car will be running not as predictive as it should be

sinyih is a heavy car, try not to jump as much as change it to a metal spur gear

Hi

i only toe in for fornt ard 3 degree and it went quite striaght....so far so good.
one question what is TX EPA? my car just went into A&E bang into the curb while drifting heehee...

when I lean the engine it always stall when wack full.....need to re-tune the engine once changing all the parts.

EPA=End piont adjustment

die when full throttle can only be two causes, too rich or too lean, check your glow plug is it distorted (mean too HOT). dont be too greedy to lean the engine, you might just lean it beyond the sweet spot, so as to call a "flame out". it can be your low speed needle that is too rich, but this rule doesnt apply if you glow plug is distorted. i would say that you turn your High speed needle 4 turn out,3.5 turn out for your low speed needle, this is rough base setting for the carb or any engine. tune your HSN before LSN and dont be too greedy on the leaning as some of the engine is not built for aredenline rush, just for bashing. you might just blow your engine.

toe in 3 degree on the fornt will definitely give you good straight line stability, but it will throw your handling of corner out of the window, the car will not response very well to turn. try and experiment with toe in and out, you will feel the differences. I think racers set up thier car with toe out to increase turning responses and to increase straight stability using other factors.

any different for front toe in or toe out? for the rear how to set whether toe in or out? there's nothing to adjust...

[technicapot]

to toe in or out for the fornt you adjust the the steering rod, for the rear you need to change the caster block for the rear to toe in.

thx, normal what is the setting for the front toe in?

[technicapot]

something like max 2 degree toe in

[fuse]

normally we all run toe out 1 degree each front wheel
and 3 degree toe in on the rear 1/10 nitro cars

yup, toe out 1 degree on the front, but I run only 1 degree toe in on the rear. more responsive in mid corner turn
