Yes, why didn't you post it here?

my PTE 680cc Settings.

Scaled to 650cc

Volts:

4.6875
7.03125
9.375
11.7188
14.0625
16.4062
18.6768

Latancy:

3.312
2.184
1.416
0.960
0.696
0.480
0.360


will this work?

It might work, but I think that injector scaling number is too high. PTE 680s flow like 650s at best, and typically the scaling number ends up being lower than what the flow rate is.

Here are mine, and they get the trims within +- 1% most days.

Injector size: 621

Injector Battery Voltage Latency Comp

Volts:
4.6875
7.03125
9.375
11.71875
14.0625
16.40625
18.603515625

Latency:
3.825
2.13
1.44
1.05
0.8099999999999999
0.63
0.48

Also I would want to half my trim since I am running 680cc injectors correct on the Coolant temp Fuel Enrichment?

I don't think that factor gets added until near the end of the fuel calculations, so if that's actually the case then you wouldn't want to edit that table since you still want the same enrichment, and the injector size is already factored in.

You do want to reduce the cranking IPW table by about 40% versus the stock table though, as that is just raw pulsewidth so the injector scaling isn't factored into that automatically.

so ipw stock is
ENGINE TEMP
-26
-0
18
45
68
93
122
171
180
mS
280.8
180.0
117.6
69.6
44.4
30.0
20.4
9.6
9.6

Just change the mS?
112.8
72.0
46.8
27.6
18.0
12.0
8.4
3.6
3.6
is this correct?

[mjannusch]

Right idea, but you reduced by 60%. You want mS * .6 = new mS. So the first value would be 168, not 112.8.

100% - 40% = 60% = *0.6

168
108
70.8
42
26.4
18
12
6
6

[ieatsushi69]

so after this I have added the launch control on and cel knock sum if greater than 5 on.
Changed what you showed me.
What is next or needed?
Anyone know how to flash my ecu to lie to the emmissions test? I lost my tune for that..... :/

[ieatsushi69]

So I did what you said car idles like shit now. Can you all me? 815-546-7233

[ieatsushi69]

I'm a blow this damn car up soon if I don't get help... I just parked the car... Something in my tune is not right,...

please correct where i went wrong

[mjannusch]

Post a list of ALL your modifications, and the .bin file of your current calibration and I'll take a look at it.

What year is your car? Federal or CA emissions?

[ieatsushi69]

WHAT SIT I USE FOR uploading?
federal.
year is 91 with 93 engine.
