Hi
Been reading up on the EOIT settings
Can you clarify the TDC position... I'm guessing 0 timing is TDC at compression ?
This is the Stock 1995 Z28 table.
DegC Deg Hex TDC+
spk btdc
0 0 0 TDC
-40 2 20 180 180 bottom of power stroke ?
-28 2 20 180 180
-16 2 20 180 180
- 4 2 20 180 180
8 4 40 360 0 TDC exhaust
20 4 40 360 0
32 4 40 360 0
44 4 40 360 0
56 5 50 450 90 90ø down on intake stroke ?
68 5 50 450 90
80 6 60 540 180 BDC (Bottom of intake stroke?
92 6 60 540 180
104 6 60 540 180
116 6 60 540 180
128 6 60 540 180
140 6 60 540 180
152 6 60 540 180
Each 90ø is covered by 16 points so 5.625ø == 1Hex value
My cam is about 56 degrees overlap guestimating 34+ degrees bigger than stock
6 x 5.625 = 33.75
7 x 5.625 = 39.375
so try adding 6 ... should have it at 573.75
So fired it up let it idle for a while to warm up
then played with EEhack eoit settings
The table opens with a value of 270 which i guess is a 3 (30H) on the table.
Moving the slider affected the fueling until CL settled down again so it is working.
Initially I moved the slider a few points at a time without major improvement
dropping the slider down to 96 seemed to give the smoothest fueling
So I stepped 90 degrees at a time and reset BLM's each time until it settled...
BLM's were
96 110 120 & 113 121
186 121 123
276 105 128
366 108 128
456 108 128
546 108 128
636 108 128
714 113 131 & 108 134
With Control off (back to 66H)
Resetting BLM's several times settled on
118 121
120 121
123 124
engine temp down to about 86C but smoking & spitting water - crap throttle, response boggy and hesitant.
I've not driven the car yet, it's too cold wet and dark.
I'll see if i get 5 mins tomorrow.
Anyone else played with these settings yet?
Thanks
Mitch
