should i get the switch table?
what do i set the egr on and off mph to, and the egr on and off kpa to... also should i back off timing and if so how many degrees?

any other things i need to kno or take note of?
i have to take off the egr becuz the intake i have, has no egr....

 

anyone?

 

You can either set the temperature thresholds really high, or the use mph thresholds.

 

Brutal just posted in another thread:

I use the 730 ECM, and just by taking it out does not mean that the ECM is ignoring the EGR. I had to uncheck it in the switchs window, then turn the enable temp way up (254*C)so the ECM is not "looking" for any EGR. If I didnt do it this way, I still would have EGR enabled, but just would not throw a code. There was some writing of this posted by Grumpy, I believe.

 

As mentioned by Ronny (for the $8D), unset the diagnostic flag for the $61 code too when you set the EGR enable/disable temperature high.

 

i should have metchend that its for a 1228063 ecm, im pertty sure theres diffrent ways of doing it for the diffrent ecms

 

anyone?

 

Tell ya what (put yer flame suit on), program a bin with the EGR mph enable/disable speeds set to an unreasonable value, disable code 32, and try it...

You are using an (uncommonly used for diyefi) ECM, not many folks here have the exact answer you are looking for in their back pocket.

 

what about adive timing? dont you have to knock it back a bit so the engnie doesnt detanate? but how much do you back the timeing off?

 

you won't have to mess with timing since your actually disabling the EGR in the chip. If you don't disable it in the chip you'll end up with too much timing without the required EGR to keep everything happy.

 

There are different routines for EGR. Depending on the code you may just disable the activation of the EGR solinoid BUT still be using the EGR spark advance. I try and disable everything to be sure that it doesn't come on. Do a search for the specific ecm and egr disable. Some mask's require special ways

 

yes witch i dont want im still learning,
just want to take off egr since the intake i have doesnt have egr on it and might as well strat somewhere since i got all the chip bruing stuff....

this might be dumb but what is
inital spark advance,
main sparck bias
main spark extended rpm limit,
rpm slope,

once i start data loging and such all catch on to this stuff, iv looked for pages explaining what exscily it does or means, sorry if i come off as stupid but id rather ask then pretend i kno

 

Initial spark advance is what your distributor is set too. You set the distributors base timing or initial timing, same thing different words, to something like 8 degrees. Now you need to let the ecm know that it's set to that so that 42 degrees max timing is 42 degrees and not really 50! Clear as mud? It's just telling the ecm where the engine stands, just like setting the injector constant size. You COULD lie to the ecm but why? Very rarely now do you need to lie to an ecm to get the desired results.
Main spark bias is to allow for negative spark advance. In other words, spark retard. The main table is stored in the chip as non-signed data 0-255 decimal. The conversion to convert that data into degrees of SA is X*90/256 . You can't get a negative number so that's why there's a bias value. This value is subtracted off of the main table so that you can get a negative value when you need it. So now the conversion is (X-bias)*90/256 where you can now get a negative number because of the bias . A perfect example of needing a negative value is on the coolant temp table. When your engine overheats you want to pull out timing (retard it some) to keep the heat OUT of the combustion chamber and into the exhaust system! There really isn't much use for a main SA bias on the main table but some people might use it, it's just there if you need it.
The c3 TBI code is funny. To save rum they use a slope SA adder. What it does is add SA up to a set RPM and by a specific adder per 1000rpm. So let's say your main SA table ends at 3600rpm and the value is 30 degerees. Let's say you want 32 degrees at 4600rpm but want 32 degrees at 6400rpm! What you would do is set the max RPM for slope SA to 4600rpm and set the slope adder to 2 degrees. It's that simple. Nothing too complicated but might be tricky to visualize... everybody's different (hence all of these darn languages in the world).
If you've still got questions let me know. I want that to be clear. Come up with some examples of your own and I'll tell you if you've got the nack or not.
