#3522 80 LB Short Body Fuel Injectors, Set of 8 # 15903 60 LB Short Body Fuel Injectors, Set of 8 The Pro-Flo 4 forced induction update support two fuel injector sizes: 60 lb and 80 lb. The sensor alone is a Bosch 0 261 230 042. Since this sensor is both a MAP and air temp sensor, an adapter harness is included to make it plug-and-play with Pro-Flo 4 wiring harnesses. This sensor can be added to an existing manifold with some minor custom machining. This sensor is included on most Edelbrock EFI superchargers. This sensor has 4 pins and combines a 2.5Bar MAP sensor and air temp sensor in one. #3547 2.5Bar TMAP Sensor & Adapter Harness OEM part number is GM or ACDelco 12615136. This sensor as 3 pins and will take the place of the standard 1Bar MAP sensor that's included in all Pro-Flo 4 kits without any modifications. The Pro-Flo 4 forced induction update supports two different MAP sensors for boost: A 1Bar MAP sensor can only read up to atmospheric pressure and can not sense boost. First, the standard 1Bar MAP sensor that's included in all Pro-Flo 4 kits can NOT be used for forced induction. If you choose to go forced induction, there are some items you'll need to outfit your Pro-Flo 4 system with. Now that you've got the procedure handy, you can follow along with me in this video where I go step by step and show you how to update your firmware. You can download and print a copy of the update procedure here: PF4_v65_FW_Update_Procedure.pdf If you have been using Pro-Flo 4 for a while and have dialed in all your settings and are happy with how your engine has been running and don't wish to make any changes besides updating to the new firmware, tap the YES button to open a PDF of the firmware update procedure. If you are an existing Pro-Flo 4 user and your E-Tuner 4 app has been updated to v4.0.1:7, the first time you launch the app and connect to your ECU that's running either v50 or v53 firmware, you will see this pop-up:


Starting from this point forward, all new production kits made at Edelbrock will come with ECU's already on v65 firmware and tablets already loaded with the v4.0.1:7 E-Tuner app. If your app is not automatically updated, simply visit the Google Play Store, search for the E-Tuner 4 app and install the update. Most existing users that have an Android device with active wifi connection will most likely have their E-Tuner app automatically updated to version 4.0.1:7. The firmware v65 update is being distributed via a regular E-Tuner 4 app update through the Google Play Store.

THIS RELEASE IS NOT A FORCED INDUCTION ONLY RELEASE. NOTE IN BOLD ABOVE THAT ALL EXISTING PRO-FLO 4 USERS SHOULD BE UPDATING TO V65 FIRMWARE. The purpose of this thread is to provide info on this new update, all the changes that have been made, what additional parts may be required and how existing Pro-Flo 4 users that are naturally aspirated will update to firmware v65. New features and functions have been added to the Pro-Flo 4 ECU firmware and E-Tuner Android app user interface to support forced induction engines up to 1000 HP and 15 psi of boost. It's always been our goal to have the simplest and easiest to use performance EFI system on the market and it was important that we carry these same attributes forward with this new addition of forced induction support. We spent quite a bit of timing implementing all the necessary system changes to support forced induction while keeping with the Edelbrock tradition of "EFI Simplified". That's right - we've been mentioning it for a while now and it's finally here - FORCED INDUCTION support for Pro-Flo 4!
