I am in need of a base map to get my car running. I have been searching around quite a bit and have not come up with much. I have a used PFC and datalogit, no competent tuners in the area and would really like to get this running. Here is a list of my setup and a link to my build thread (which I need to update) https://www.rx7club.com/single-turbo-rx-7s-23/spec-3574r-install-965464/


3574R single
bosch 1600 secondaries
full exhaust
Vmount
HKS twinpower
bur9eq leading and trailing

Any help is greatly appreciated!
Thanks,
Dan

 

Well, after a fun day of dealing with an ignition issue and a flooded engine I finally got the 7 running and thru the idle process for the most part, I still need to make some adjustments to the TB though. I basically copied what looked to be good IGN map and set the rest according to the FC-Edit manual. This is my first experience with the PFC and tuning for that matter so I am nervous and excited at the same time =)

 

let me know how you make out, I have the exact same setup.

 

I am still working on the idle / light throttle putting around...or I should say it is stuttering/hesitating terrible on throttle tip-in. It tends to run a bit better under full elec load but still hesitates. I will be pulling the plugs later tonight and double checking my grounds. Other than that I may just start over with the base mod map and see how it goes.

 

did you see this thread https://www.rx7club.com/power-fc-forum-47/accel-settings-inj-vs-accel-tps1-eliminate-stumbles-916169/ ?

 

I found that a couple of days ago, and implemented the new settings last night, as well as adjusted my tps to a higher base setting (still within range). It did help quite a bit, but there is a stumble present, its almost like the injector shuts off for a split sec when rolling in from idle, or punching the throttle during engine decel; rev to 3500, let off, punch at 2000 = slight delay-lean-then rev. Its really strange...

I do have a couple charts of before and after I changed INJ Accel and I will try to get them posted yet tonight.

 

Here are my charts from last night, just idling, no load. I did not set a lower limit on the INJ but if you look at the RPM you will notice that id drops while the injector shows that it is firing...

 

This is better:

 

I have been playing with different settings for the INJ Accel and just can't get rid of the hesitation... it only happens 60% of the time so I am almost wondering if it is an elec / mechanical issue. I am going thru my last couple logs trying to get the AFR more stable for cruising / light load, maybe if I set the idle higher it will help with the stumble?
