Since I did not want to send all my money to ZZP for a canned tune and no way to check or change, I decided to get HPTuners myself and watch a lot of youtube videos on how to tune the car myself.
Starting from stock, I pulled the file to familiarize myself with the parameters
I then learned to log and set up the scanned engine parameters
Once I understood enough of what I was looking at I practiced MAF only and VVE tuning to get the calibration closer to my engine prior to adding the supercharger. Once you add the supercharger, MAF, VVE, Injector tune, MAP parameters, TB parameters all change so the more you know and understand the system, the less variables you have.
Once the engine was tuned better, I changed to the new injectors on the stock engine. this way, any mismatch of tuning was not the MAF or VVE but the injectors. LESSONS LERNED: change only one variable at a time to diagnose issues. That is how I found the faulty injectors and could quickly adjust the parameters to fit the engine.
With the injectors settled, then I started tearing into the engine for the change.
All the old stuff removed....Just like the donor, LABLE EVERYTHING
Many many trial fits with the lower intake manifold showed a few things.
- The stock dipstick tube does not fit directly. The bolted flange hits the front and the bend does not allow the manifold to sit in place. I removed the tube, put a deeper S bend into it and cut the flange off. The starter wiring is no longer long enough to reach under the manifold to the LSJ alternator. Rotating the wires and getting a longer alternator to starter wire allows the intake manifold to fit. The 2.2 and 2.4L NA engines have their intake manifolds secured to the head with 6mm studs and bolts but the LSJ manifold is mounted with 8MM hardware. Some people drill and tap for the larger size but I found 6mm ID x 8mm OD spacer sleeves that centralize the manifold and gasket to the head so no port mismatch.
- The bracket under the manifold had to be drilled out some as the block bolting on the 2.2 and 2.4 is larger than the LSJ, quick work with a drill and it mounts up with new hardware. The cross bolt from this bracket to the lower intake manifold fits into a machined hole. Was their supposed to be a bushing that fills the gap or a shoulder bolt. I had neither but a nylon spacer filled the gap and actually makes that connection worth while at least for me.
