Here's one for mt. Cant speak to which phase but at least gets the os loaded.
128501
Remove all the Tb related channels minus accel pedal and tb angle.
Whyd you limit it to one mp? What about the odd lean knee in pe? What's the veh? Stock tune file?
Hitting cyl pressure limits...
I don't see those channels. Maybe its a gen3 thing?
K44 how did the tb angle respond with 33 degrees of timing compared to the normal 7 or 8 degrees?
Good stuff Mike.
Have also found the return to idle and idle in general is more stable with...
How does a gt500 behave?
Learned a few things from the snap to line on those. Similar to the gen3 roush.
?? and desired determines which vct mode you are in.. which determines which MP and cam timing.
desired determines which MP will be used (cam timing). all of the load dependent mp/cam setting tables are based on desired load.
but correct i was using terms loosely with cam timing/mp.
cam timing comes from DESIRED load. when your rt foot tells the ecu go from idle to 200ftlbs, the mapped points used are from the load that it has determined it needs to get to to satisfy the request...
2017 gt,
roush phase 2 kit with phase 1 pulley (85mm).
2020 gt500 injectors.
Mild Ported lower mani, port matched runners to cyl heads.
Untouched roush maft curve,
Ambient Temps mid 90's....
Yep raise the min to what ever your local baro is to keep it from it drifting down
basically what you did but i went with 29.3 or 29.4inhg. weather stations report a corrected baro, need readings from a MAP sensor or Iphone/airport etc.
I ended up locking out baro. And it drove pretty much spot on iirc. There's another thread where its mentioned the gt350 has baro tables that don't show in hptuners. Frpp tune allowed a much larger...
air load is the non sae. repoll in the scanner.
mike hit it on the head, there are just limitations on the obd2 port that the scanner does a very good job to overcome but the data down to a few...
thanks for sharing mike!
yes a write up of some sort would be helpful!
yep it drifts low. im 500ft above sealevel and baro with any external map sensor is usually right at 29.5inhg. if that was the last place the tune had learned the baro too, it will start there with...
im starting to adapt the same mentality. adjust what was changed and leave the rest alone.
na the gt350 tb caused the baro drift. it shifts the whole etc vac model so its pulling angles from an...
personally, im not a fan of messing with the maft curve unless you know that is for sure the issue (no maf data etc). i am in favor of using the low inj slope to get fueling in range if this was the...
put the maf curve back to what ever jlt said it was. lock the learned baro to something reasonable for your altitude.
usually the learned baro tanks the etc vac and as it keeps adapting it...
Timing will need adjusted after cams are moved.
The cams dictate which map point. The core of the ecu is the torque request and then how to deliver it with cam angles per load/rpm followed by...
Best I can find, roush started adding a map sensor for baro back in 2018 on the gen2 kits.
Correct though, actually a map sensor.
My kit uses the 2nd imrc sensor input and adds a map sensor...
very cool add on, i know several of the supercharger OS use at least one for the manifold temp and roush uses the 2nd sensor input for an added baro sensor.
seems like the next step would be to...
post the tune wildhorse. i suspect its locked but lets see
Ive found the fine tuning on the 18 mani is the SD not being accurate on the IMRC opening, there is a moment of it clipping the inhg...
to echo Mike, here is the gen2 specs plugged into a shared gen1 cam visual that another member created. slight difference ive found with compcams spec cards is centerline at 109 parked for the...
