Agreed......whenever fixing major issues that affect the ECU, get and write down codes as well as LTFT's, fix Issue, reset ECU (clear codes with scanner, kill ECU power).....let ECU relearn. Recheck, see what happens.Did you reset the ECU after fixing the leak? Your trims could've been outta whack.
All of that sounds amazing! It's unfortunate that the 1500 are on the expensive side. But at least I'm in Florida and we don't do any emissions checks or inspections at all. When it gets closer I'll do some research and see if there's something simpler in the Haltech line that will do what I need. This car is a daily and it'll never run E85, so the Flex Fuel option is not something I'll ever need.Haltech Elite 1500! Can do gear dependent boost control and also has damn near close to stock knock sensing. It can retard timing and place it back in once it stops detecting knock. Oh and Flex Fuel capability built right in. AND it has the ability to spit out basic OBD codes. It cannot do emissions readiness checks so if your state requires that your outta luck as no standalone supports that.
You make some very good points lol. And if I remember correctly there's no plug and play harnesses for any standalone out there, so it will be a custom wiring job either way. Plus having to figure out what to do with the FIC wires that were tapped or intercepted already.Keep in mind you get what you pay for. Haltechs support is awesome and they are constantly adding new features via firmware updates. Oh and have damn near perfect base maps that would require little to no tuning. Good luck finding that with anything else lol.
Over the course of this whole mess I've replaced the IAC with the gasket several times, replaced the intake manifold gasket, and checked for leaks multiple times.I can only suggest checking the IAC again... Maybe you have a vac leak from the IAC gaskets or the intake manifold or something?
With regards to standalone ECU's i've had great success with the Link G4+ Thunder...
To be honest i've probably gone one step further than most as i wanted to maintain stock-like functionality whilst having full control over the ECU calibration.
I have the Link ECU integrated with the factory dash (working tach, speedo, ECU lights etc), i even have the stock obd-ii port wired up.
With my setup i've integrated the factory A/C controls and oe pressure sensor etc, i'm even using the oe purge valve and fuel tank pressure sensor.
For traction control / launch control i've switched from the the oe cable throttle to a bosch e-throttle.
I've then integrated the oe steering wheel cruise stalk, 4x wheel speed sensors, oe traction switch, brake switch, clutch switch and also the dash traction lights.
I've even got the flat foot shift working as i'm using the oe clutch switch as a trigger...
