I realize they teach this at EFI101 but I've never seen it make a difference - with the possible exception of, if you are having to use resistor packs with the electromotive, which slows down the open/close time - is that the case here? if your particular unit supports low impedance injectors without resistor packs, then I say scrap the sequential idea (two sensors to fail versus one) and go with the Pantera coils on wasted spark. Let me know if you can't find the answer and I'll call one of my friends there. my guess is, their timing algorithm needs to see that well before TDC however. We lock the timing at 10* and when we hit that, we change the lock to 20* to see if it follows.īobWhere the Cam sensor trips the counter is going to have to follow the Electromotive directions. I'll pull the plugs (Doh!) it'll speed up the cranking speed, the injectors have been disabled when checking the timing. The rpm signal appears fine, but the timing is jumping all over.
Is that right, or should we have it trip the counter at 40 BTDC which is the max timing we'll use? I realize that having the injectors sequential is of dubious value at WOT, should we just use multi-point or batch? We went to sequential to help control the 1000cc injectors at idle. We set it up to have the cam synch trip the counter at TDC. This parameter, as it does not apply for the given trigger. If this field is grey and not able to be changed, then ignore The trigger tooth should be chosen so that the trigger angle can beĭialled into the range described below. ? Tooth Offset - The tooth offset is the number of teeth from the Home signal to the tooth that isĬhosen to be the trigger tooth.

For more information on how to set the tooth offset and trigger angle correctly please refer to the quickstart guide you received with your ECU.
Angle between triggers for a 4 cylinder is 720/4 =ġ80 degrees. Your trigger angle must be between 32 to 180 degrees. If the largest ignition advance angle you wanted to use was 32 degrees on a 4 cylinder engine, then Must be between the largest intended advance angle and the angle between trigger events.Į.g. The trigger point is the tooth defined by the Tooth Offset that is described below. For multi-tooth triggers such as those found on Toyota?s, Honda?s and Mazda?s, Trigger Angle BTDC - This is the angle between the trigger input and the corresponding piston's I would look to the other E-tuners with good reviews here on NASIOC.Re: School me, Crank trigger angles, tooth offsets, home signals. But for anyone thinking about an E-tune from him. I do not question his tuning abilities and I am sure there will be many to reply stating the amazing experiences they have had with his tunes. I have had E-tunes from another tuner (I will not state the company/tuner, as I do not want it to seem like I am trying to promote another company), and the turn around for revisions were always less than 48hrs.Īs stated previously. If you do not have the time to E-tune, then do not recommend to me, to get an E tune from you. At this rate, I should expect my E-tune to be done in 3.5+ Months. He also states you get unlimited revisions in 4 weeks. On his website he states the E-tune averages 10-15 revisions.
I have an issue with the time in which this is happening. I have no trouble with his ability to tune. The couple revisions he has replied with, have been solid. I have attempted to email and resolve the issue with Mikey. The issue here is that I have received 3 revisions from 07JUL-Now (9AUG). But the wait does not change.Ģ5 July 2014: Receive Revision 3 (Requests Cruise log, low boost (15 psi) 3k-5k Pull)ģ1 July 2014: Receive Revision 4 (Requests More low boost (15psi) 3k-5k pulls) *Replies in email stating, "Sorry for the wait, back from travels." Ok I understand vacations/work happens. This isn't preferred, but in KS there is not a lot of options and I felt confident an E-tune from Mike would be solid, due to the amount of support he has.ħ July 2014: I receive Revision 1 (Request Idle, Reving, Cruise Logs, NO WOT)ġ7 July 2014: Receive Revision 2 (Request Idle, Reving, Cruise Logs, NO WOT) After a couple emails back and forth, he stated he thinks it would be better to just do an E-tune, since he does not have a time frame on when he will actually be here. He could not confirm which date he would be coming. I emailed Mike to get on the list, as I have heard nothing but good results about his tuning abilities. Back in June a local member created a post stating Mike Botti would be coming to Wichita, KS to conduct some tuning.
