Other than turning the timing lock on and off for setting the initial timing, is their a setting for the timing? I'm still reading some 20 something degrees btdc and cooland temps on the highway are 90-94 degrees celcius, thats around 195 to 200 respectively. However, I want it cooler. Like around 82-84. Also, I went to Atlanta this past weekend and got in some good tuning time on the highway and the car is running alot better. I had the afr's anywhere from 12.5 to 14.5. Now it is set between 12.5 to 13.5. That should be a good afr, correct? My idle is still extremely full rich. And I don't have the best transision between gears, I get a little backfire pop between 2-3 and 3-4. Any suggestions

Get your cruise afrs to 13.5:1 to 14.7:1. this will be ideal.

from 05HG to 00HG go from 14:1 and bring it down to 12.5:1.

get your idle to 12:1-14:1. depends on the engine. see where it wants to idle. Put around 5-10 degrees of timing in the idle. (can lean it out more).


On your cruise. between 20HG and 05HG run up to 35 degrees of timing.(use less fuel).

Also check that your back off isnt too rich.

What do you mean by back off? I think it is too rich

These are my current settings in row 3. The first row I took from the forum of someone running pretty close the same setup I am. I started there and went to the second row. It still ran really rich. Then I went to Atlanta, Ga.( about 5 hrs away) and did some tuning on the laptop while driveing down there. Row 3 are my final settings to date. I haven't done what you said about the 35 degrees of timing yet. After I do that, my temps should go down, correct? Also, any correction you see that may need to be done would be really helpful. The car runs fairly well, well enough to outrun a 05 Mustang GT 350, but I it has run better before I put the ecu in. My old setup was really outdated and problematic.

Also what are your afrs like on boost?
THey look very rich especially coming onto boost?

Thanks for the help. It's been awhile since I was on and the server was down so I couldn't thank you earlier. The timing seems to have helped and my afrs into boost are rich. The car is still rich pretty much everywhere except for highway cruising. This is too far advanced for most of the people in this area and consiquently, I have no one to bounce ideas off of or take for a ride. I guess maybe I'll have to give up the keys and let someone else drive and I tune but not one of my favorite solutions.

My cold start up is still bad. I have to hold it at 3k and if it starts to drop and I try to make it idle; (1) it won't, (2) it starts poping like its out of time and stumbling like its out of fuel or maybe getting too much( i don't know). I have to stay there for a few minutes until it gets warm enough to idle on it own, but even at that it still runs 11.0 afr's at idle. When I get it to idle, its really rich. When I start to make the afr's move and lean out some, it dies and wont idle. Could that be a combination mechanical and ecu issue? My throttle body is modded and has nothing but the butterflies in it. No cold start or anything. It does have the dash pot with the button to slow the throttle linkage down when it hits it. And the tps on the other side. Thats it.

Again thanks for the tips.

The throttle body is most likely making things very difficult for you.
If i was you id bolt a factory throttle body back on. With all the butterflies in it.

Ive found most rotaries like idling at 11.9-12.5:1 on idle. any richer and i reckon your injectors are leaking or your fuel pressure is too high or you engine is low on comp.

are you using a AFR meter?

lean off the cruise.

Try adding more fuel to your cold start and see if it helps.

Yes, I have a AFR Meter. I have both the wide and narrow band. I'm using the narrow band now with the wide band readings off the hand controller. If I need to switch to the wide band, I have one, just not installed right now.

My injectors are new, fpr are new, engine has 5k miles on it.

the cold start is the af_ste correct? It's at +10% now.

New question, When I crack the engine, it has to turn over for about 3-5 seconds before ignition. Is there a setting I can manipulate to get the engine to ignite instantly?

No. The microtechs wait for a complete cycle from the CAS before it actually gets everything kicking.

the cold start is not af_ste


Their is a map called Water that has different temperature ranges. this is your cold start map. go to the temperature were the car is giving you problems and add some fuel.

**** off the narrowband and put the wideband on.

For your cranking. i can help you but you need to show me your IDLE map and your LOAD map and i can look at it.

Just realised you already posted up your maps sorry mate.

In the idle map.

Add more fuel to the 05HG and 00HG and see if it helps it.
