I have a 3rd Gen with single Turbo (TS04) MSD egnition on the leading, 850cc prim. 1600 Sec. Street ported motor, Haltech computer, and set to boost about 20 PSI. Engine has Low compression rotors with 3mm apex seals. NOW here is what i need to know. im going to the dyno tommorow and need to see who can help me by telling me what the correct timming should be on IDLE, then into transition and Most important under full boost and load at top end. any feedback by tommorow morning will be greatly appriciated.

Thanks in advance

Rob

PS!! If there is anyone that is willing to Send me thier current curve for starters that would really help alot and save a fellow rx7 owner some money on the dyno time.

Sorry, I forgot to mention this is for a map on an E6K

 

here is where im at

About 10* at Idle
35* to 38* in vacume in the upper rpm's
in vacume at about 1 or 2 inhg about 28*
then going into boost 1 or 2lbs 25*-26*
then from 6 to 9lbs 21* to 24*
then from 9 to 14lbs 17* to 19*
then from 15 to 20lbs 16* to 12* maybe even 10* at full to be on the safe side.

what do u think of this?

 

Every motor is a little different, specially you have a street port, done by different builder. There is too many variable, not knowing exactly how much overlap, what the port timing is...
Best is to tune this out on the dyno, according to the knock and peak torque.

 

Are those absolute values off the Haltech E6K, or are you adjusting for base idle?

Since the Haltech E6K cannot do - ignition timing, if you set idle to stock -5 or -10(?) and then punch in those numbers, you need to subtract them.
