Re: Toyota Hilux 2LT
Cameron, I agree with your post about other resources. That is something that everyone should try to do with their individual vehicles. Joe and I had an off forum discussion about his vehicle. Here is what I replied -
"Unfortunately, every engine is different. Even the 2LT has a mechanical injection pump and a later electrical injection pump, so the techniques to tune the same basic engine will be different with the different pumps.
What I said about gettin a factory manual is the most important step. You need to find out how everything works. Once you know how it works, then you can tweak it to the way you want it.
The thread on the Surf forum can assist you to look at concepts that may or may not be implemented on your vehicle. You can purchase a boost guage for about $60. I didn't install it permanently, I ran the hose in my side window and taped the guage to my dash. All I wanted was to to see what was happening in the manifold. Once I knew how the pressure rose, at what RPMs and at what pressure, then I took it off. The guage is used for diagnostic work, not as a neat looking accessory.
On your system, look for something that delays the extra fuel flow while on boost. There may be an emission control function that delays the fuel flow so the vehicle produces less emissions in traffic.
Sorry I can't be more specific about your Mitsubishi."
When I purchased the Hilux, I didn't know that the engine was a transplant from another vehicle. It was only by doing a bit of research that I relaised it probably came out of a Toyota Surf. Once I had that bit of information, I then went to the Toyota Surf forum for some advice. From there I was able to piece together enough information from various resources (including a French site that had drawings of the 2LT injection pump, and also a British site that had drawings furnished by a fellow in Pakistan!).
Having access to a factory manual would have speeded up the process, but by some convoluted researching on the internet I was able to find what I needed. Recently I have used the Surf forum for some suspension research, again with success.
There are a lot of different forums available on the internet with many people who have probably had the same problems as you posting to those forums.
