Ignition Timing Tuning explained EVO Ecuflash 

i cant tell you how grateful I am to come across this. this is so helpful. I finally have a better understanding on how this timing stuff works. time to go blow my engine.

So far the best video on RU-vid explaining how to calibrate ignition timing of a turbo car!got the concept clearly...thanks!

Love how you teach very slower and consistent

You have the best explanation on RU-vid

Grate Video! But, you have one mistake, when an engine's stroke is increased it's connecting rod has to be shortened ,theirs only so much deck- height space, to make room for the increased stroke. Moreover, The reduced length of the conneting-rod decreases the rod to crank ratio. Thus, causing a reduction of "TDC piston dwell" , when the con-rod length is increased the "TDC piston dwell time, in crankshaft degrees" is increased. Also, the opposite happens in BDC, The "BDC piston dwell time", in crankshaft degrees is decreased. Rod to crank ratio: is half of the stroke divided by the length of the connecting rod, this is because the crank pin actually makes a circle as it spins and the radius is used to calculate the "rod to crank ratio". I'm ending it hear... I already wrote more than I the time that I wanted to spent.

Seriously thanks man I been trying to understand timing for a while and couldn’t fix a simple explanation, but this gave me a good idea of how it works … question tho , do u just add timing to see how the motor responds and keep adding u till u see no more power or untill detonation occurs? Like when do u know “that’s enough “

One of the best tuning vids I've seen so far. I'm wondering, how would this change if my engine is NA, I guess not having a turbo would let us have earlier timing?

Dang great video bro. Can you do a step buy step assembly on the 4b11? Like how to check the clearance on bearings and rings?

Need more step by step tuning videos 😢

Best video for ignition tuning 🔥

Hey I love this explanation. Can you do one for Subarus?

Thank you so much for this video Very helpful for beginners

New subscriber here. Thanks for the teaching.

Question, a few times you referred to the top horizontal load axis as psi, and you pointed over the 250 and 260 kPa load cells as 25-26 psi. Were you just talking in general or have you set up your cells to refer to actual psi units and NOT kilopascals? As usually any stock mitsubishi load map will have kPa ranging from 0 to 150 or 200, which correlates to boost load. Like you said, from 0 to 100 is effectively vacuum, and from 100 to 200 would be in bars. so 120 would be 0.2 bar boost, 150 would be 0.5 bar and 200 would be 1 full bar of boost (14.7 psi or 100 boost kPa).

Thank you fam you the man

Yooooo thanks got a sense, now time to hook my bike and read all the param

Great video. Question I’ve got at 8 with fp black and s3 cams. I’m getting some knock at higher rpm’s (6800 +) with my peak timing about 1-2 degrees going to 10 at redline. Does 10 degrees at 7k rpm sound like it’s too much for 24-26 psi on 93? I’ve played with AFRs rich rung up from 11.4 all the way to. 10.9 and still getting knock in this area. Would appreciate your insight

Hey love your videos, will you be making a VID on how to tune a evo ecu with ecuflash? i realised your ecuflash has alot more stuff on the drop list than me

More stroke length does give more torque relatively speaking.........BUT it comes at the price of rpm potential. Its a universally observed limitation that long stroke engines (all else being equal) cant achieve the same rpm without having a catastrophic failure due to the extra piston speed (for the same rpm) and conrod loading. Its not a free lunch.

seu video é muito bom, ganhou um inscrito!

Thank you!!

THANKS!!

If you have a EBCS, and your target is 28 psi with an FP black. If you hold 28 pounds until redline, would you still target 14-15 degrrees at redline. Or would it be the 8-9 as show in the chart?

Good stuff

Can you map this ignition timing table like on a chart showing transitions?

Dwell time is the charge time of ignition coil pack. Not the time of piston at tdc....

So, 6° is your preferred maximum degree at top tq on the 4G63. what about the 4B11? what'd be your max ° at top tq?

Trying to tune my Prelude BB8, JDM, type S with Greddy EMU (piggybcak). It is all motor with intake, exhaust, camshaft upgrade. I can handle fuel tuning based on wideband. My questing is how to tune timing/ignition? When should timing be retarded or advanced? There is no dyno machine in my area (Belitung island, Indonesia). Tuning must be done on street (fortunately no speed limit on public road).
