This post will be in support of the Haltech Elite 1000 series ECU install for our SRT4s. The system looks pretty straight foward plug-and-play so any parameters outside of the paralleled plug system from the cars wiring harness to the Haltech will be indepthly covered. These systems are not cheap so I understand why people go for the AEM but since I've have the opportunity I believe the ECU system diserves an install thread.
I'll attach pictures as I go and include previous dyno pulls from the DSP program that went out on the car compared to the Haltech unit. The dyno pulls will vary greatly though as the car has been swapped from one fuel system and injectors to a more capable system as the car was seeing fuel cut at 4800 rpm on the dyno.
The car:
04' SRT4
Stage 3 ECU with 3 bar map/tip sensors
50 trim @ 25psi on e85
Manual boost controller & adjustable aftermarket wastegate
3" exhaust (stock style out the back)
AFX Wideband 02
Stock style coil and wires
Plugs gapped at .047" right now on the get by tune.
Stock head
Forged rods and pistons 8.8:1 CR
Stock crank
Big front mount intercooler
FIC 1100cc injectors-(ran 770cc @ 105% duty cycle via 58 psi on e85 at 4800rpm)
Boomba throttle body
Custom log style intake manifold
Perrin fuel rail
Aeromotive fuel pressure regulator
Mishimoto oil cooler
Walbro 255 intank fuel pump (no bottle neck)
Dyno stats from Mustang 2 Dyno: 388hp & 425tq with 10% loss from dyno that puts the car around about 426hp/472tq on the street if I'm lucky.
Current set up:
All system settings not changed from above are the same for the current set up.
Fuel:
2.5 Gal surge tank- 255 walbro feeds the tank and circulates fuel back to the main tank at all times. Bosch 044 (out of tank set up) pulls from surge tank to feed fuel pressure regulator,fuel rail and then recirculated back to surge tank.
-6an feed lines, -4an return lines
Fuel Injector Development 1300cc injectors @ 58psi.
New 3 bar MAP/TIP sensors from Modern Performance
ECU burnt out the injector drivers (my fault for starting the car first before shrink wrapping the crimps- to very they worked). So I'm waiting on the Haltech Elite 1000 unit for the SRT4 this week. More pictures and info to follow...
