Re: Mazda MX-5 NB - DET3 FIT with BOOST
You WBO /EGO corrections ? Yes, I have it on all the time, that's the only reason I have reasonable mileage I guess.

Re: Mazda MX-5 NB - DET3 FIT with BOOST
I haven't tried, I like my car too much. But you have full control over timing retard and fuel so it will work. The issue is, that there is not an input to trigger it. But you can sacrifice Wideband input for racing, if have tuned well.

Re: Mazda MX-5 NB - DET3 FIT with BOOST
No, only MAF. MAP is on DET3 device. Please read whole topic.

Re: Mazda MX-5 NB - DET3 FIT with BOOST
Hi, I just ignored MAF and crank sensor, there is not enough inputs for them anyway. Onboard MAP is on Analog #2 i think. Mx-5 is wasted spark (2 times per 720). In batch mode you don't care about crank/cam position and it takes RPM from coil signal (Ignition In). It does not really matter, it injec...

Re: Mazda MX-5 NB MAF to MAP and timing
Hi, yeah, car run whole season like a charm with around 170HP (small turbo) and plenty of torque. When I was not pushing hard I had even reasonable mileage. Under 10l/100km. I just left MAF as it is, fortunately mazda ECU does no go crazy when you put there crazy amount of air, I think it event reta...

Re: Mazda MX-5 NB MAF to MAP and timing
Yes I have RX-8 yellow injectors (some say 420, some 440cc), mine showed on flow bench circa 430. Latest best settings is this one: https://github.com/strndy/DET3-FIT-settings/blob/master/DET3_FUEL_IMPLANT/projects/project_2016817_1710_interpolated.pbp Ignore FUEL MAP, VE TABLE is all the magic you ...

Re: Mazda MX-5 NB MAF to MAP and timing
Hi, I've found out that messing up with MAF signal on MX-5 is not best approach. I was not able to map it properly, especially with large injectors. Throttle response was pretty bad and AFR was never right. I've switched FIT mode, I firing all 4 injectors at the same time and modifying coils signal....

Re: MX-5 NB - Direct controlling of the injectors opening ti
I don't need to stay sequential, but one injection per cycle for all 4 cylinders is not enought.

MX-5 NB - Direct controlling of the injectors opening time
Hello, My MX-5 NB (Mk2) has sequential fuel injection from from factory and now when I have turbo installed, I would like to put more fuel on boost. Is it possible to convert from sequential injection to bank fire without using DET3 in FIT mode? I really would like modify signal (keep really good fa...

Re: Mazda MX-5 NB MAF to MAP and timing
I guess this will be black magic, but with forced induction, I will probably not need advancing.Jadzwin wrote:In FIT mode you can advance ignition by altering MAF signal (or modifying MAF/MAP conversion map). The lower voltage the more advanced ignition..
Thank you, this was very useful!

Re: Mazda MX-5 NB Issues
Thx man, I'll try it. I don't have turbo (yet) so I want to advance ignition on 98 fuel, maybe event e85, so I have basically two options: 1) controll coils directly (where to wire second coin?) 2) Move HALL sensor few degrees in advance and do corrections. Anyone sucessffuly converted MAF to MAP ?

Re: Mazda MX-5 NB Issues
OK, I'm able to read RPM, but when I let flow signal through DET3, I'm not able to start. I even connected DET directli on battery (with fuse), but no luck :( Settings: Retard / advance multitooth signal Hall effect or optical 8 signals per 720 Tried with and without pullup resistor, no change. Scop...
