I sent a PM to mjlkwolfe@gmail.com who is a new member and a semi retired automotive fuel systems engineer including the Steinbauer Performance link and a into this thread asking him if he would take a look and give us his thoughts. Hopefully he can give us some insight.
The price tag is big ($2K) as are the claims (70hp just by modulating fuel pulse without timing changes beyond what the stock ECM programming does or changing fuel pressures)
Good morning all:
I seriously doubt this unit can produce the power they claim by merely increasing injector pulse width.
Adding additional fuel in & of itself will not increase engine power unless the richened mixture reduces the timing reduction caused by the knock sensors.
Even then I doubt it could increase hp & torque by 20% or more.
To increase power you need to add additional boost pressure & advance the engine ignition timing while at the same time adding the correct amount of fuel.
However this unit might be a good choice to accommodate the use of a high percentages of E85 which is about 108 octane & offers superior in cylinder cooling when compared to gasoline.
If the injectors have an adequate flow rate to accommodate 100% E85 then boost pressures could be raised several PSI with no detonation concerns.
This appears to be a unit similar to the unit I put on my 2004 Nissan Titan Pickup to allow the use of E85 & avoid high fuel trim numbers.
Maybe someone else has had experience with this unit & can offer some real life experience.
Does anyone know the maximum static flow rate of the OEM injectors?
Does anyone know if the F150 injectors are a higher flow rate than the Taurus/Flex units?
Maybe our friends at Livernois can shed some light on this unit & my questions about injector flow rates
I have ordered a unit from Livernois for my 2013 SHO with the OEM performance package so see how well their tunes work
