Let me start off by saying I have searched and didn't find much on this system. I assume it isn't very popular with all the other systems available these days. I am also a Hondata guy who has tuned my own setup without any problems. I am very familiar with the software and such on Hondata. I haven't had a chance to really dig into this Tec3 yet but will this weekend.

So with out further due:
A buddy of mine just got individual throttle bodies and a Tec3 setup for his JDM ITR swapped EG hatch. A professional car audio installer did the most professional wiring job I have ever seen on it. My questions are this:
1) Anyone have a somewhat tuned map for a similar setup that can get us going instead of the base maps (Which are complete **** so far, even ones we have created).
2) What are some key pointers to aid in tuning.
3) What should we look out for?
4) Anything else that may help?

So far we got the car started and it runs but it is hella rich and doesn't like to rev above like 4000 (because it is rich).

Thanks for any help you can provide.

 

What you need is to get ahold of a wideband air/fuel unit such as FJO or Innovative Motorsports. I do not know if you are tuning on dyno or street, but wideband is a must. What size injectors are you running? And do you have a fuel pressure regulator? You might want to start at stock 44psi for wot and work your way down from there, but best info i can tell you is to get a wideband.

 

What size is your vacuum canister?

If you are going to run maps off of both tps and map sensor, you'll need a good strong vacuum signal. The smaller the vacuum canister, the better. The smaller surface amplifies the signal, allowing small transitions to be seen much better by the map sensor. My friend found it best to use a mcmaster carr vacuum log, using Hondata the maps are tuned very well with both tps and map sensor signal.

With the Tec3 unit I believe you have the option to tune off of purely tps. If so you should be able to proportion the amount of tps feedback to map sensor. For example when getting on the throttle if you dont have a good vacuum signal the map sensor will read 0psi, or full atmospheric even when transitioning through the partial throttle maps. I know that the AEM is capable of this function, I havent had much exposure to the Tec3 unit so I am not 100% on its ability.

Another tip is to run the vacuum nipples off each runner closest to the cylinder head as possible. The closer you can get to the cylinder head, the more accurate the vacuum signal to the map sensor. After fiddling around with a few different configurations on my friends itb set-up, we found that trick to help the vacuum signal as well as running a much smaller vacuum canister that what he originally had. His engine was pretty amazing, it idle at 1000rpm steady, and was 95% drivable through the maps (non-wot). I was pleased with the outcome using Hondata.

 

I'm in TEC3 hell right now myself.....

The base maps ARE absolute ****, and i've made no progress with my system...even with help from Fred at Electromotive...

Any decent working Bins yet? manage to drop your idle below 4000? (I got to 2500...but that's most likely due to the -30 weather we have now

any bin whatsoever you could E-mail me? (troya@shaw.ca) I'm desperate.
