So now i got my car running...
I need ideas in tuning fuel maps....
What do you guys normally do .....
What tools you all use.....
what readings do you all go by.......
etc......

 

Three words:

Get

A

Wideband

If you don't have experience tuning, you'll most likely blow up your engine trying to tune without one. And no, a OEM O2 sensor is of no value.

Sorry, costs a lot of money to play with this stuff.

Or you could go to your local dyno and use theirs

 

so tools needs is
1] wideband air fuel ratio meter

 

The question would be more like, if you got everything you needed, would you know what you're doing? If the answer is no, you're probably best off having someone else tune it for you.

I have no experience with the triangles, but I hear they are VERY touchy when it comes to detonation. Quite the relief to us piston-based tuners.

BTW, a Knock Link might be useful, though I'm not sure anyone here even wants to get that close to knock for anything to even register on there. *shrug*

Thats great info Ted.

 

I disagree with the old-wisdom of using an EGT gauge in tuning, especially for somebody who's new to tuning. I strongly disagree with suggesting anyone use a standard O2 sensor as any sort of tuning aid, as this one will lie to you almost every time.

Ignition timing should really be tuned on a dyno, and in conservative increments. Any tuner that cranks up the advance till it rattles, then backs it off is NOT earning the money you pay him/her. The idea is to optimize the spark advance to PREVENT engine damage, not cause damage in seeking said optimal state. A good, repeatable dyno will show the torque drop off before the engine starts to hammer itself apart, and a good tuner/dyno operator will know when to quit adding advance.

YMMV

i still need to get my factory tach working on my t2 w/e6k let me know if any of u can help
thanks,
justin

 

Sean, i know you LOVE to do everything your self but sometimes it is just more effecient to have somone else do it for you and then all you have to do is drive it. you just got your car running and it would be a shame if you blew it up again! call me and i will tune it for you for a flat rate. i have tuned just about every rotary car in houston and i more than likely already have a map that is REAL close to what your setup is.

Sorry Marcus..
I already got close to where i wanted it...

 

no need to apoligize, just offering my services :-)

Get help from a dyno shop, it's worth the money.

 

Well some of us dont have access to one within a freaking million miles! I have tried TRUST ME, Id be very happy to pay someone to tune my POS... I have even contacted key tuning people on the internet and no one will return emails or anything... I have even contacted a few of you guys from this board and same answer, only had help from one person. Its not like most people wouldnt pay. I know I would. But I aint trucking my car 1000 miles, I work too much for that.

 

If I was one of them, I apologize.&nbsp My life is a big mess right now, and my schedule is day-to-day.&nbsp I got too much crap going on, and I don't have consistent access to a computer all the time.&nbsp A lot of the e-mails, especially very lengthy ones, I tend to ignore till they end up being a year old!&nbsp I then tend to delete them, cause I'm assuming everything has been taken care of...

If you've got a friend with a wideband, you should be able to tune your fuel maps well enough to make the car run/drive safely to a dyno facility. If you can find somebody with the expertise and willingness to help you, accept the fact that you might have to travel a ways to get the help you need.

Sounds like you missed out on Matt's travels to the States. Too bad, because he's probably one of the world's best rotary tuners.
