I'll start with what I have and what I want, I have an 86 mr2 with a 91 3sgte heavily modified, I'm currently running stock race prepped, balanced, crankshaft with rods and the rods are also resized. My pistons are 9.0:1 compression .020" oversized ceramic top coated, silicone side coated pistons. The head is mostly stock for now with a valve angle regrind job and port and polish. My exhaust is a tubular stainless steel header dumping into a GT3082R garrett dual ball bearing design, the intercooler is a water/air custom setup feeding into a custom sheetmetal intake. My fuel system is a walbro 255LPH with 3/8" fuel lines feeding a 9/16" top feed rail and 550CC injectors. What I want is a standalone that has an open ended software(it doesn't need to be sent away somewhere special to be programmed just need a laptop) plug and play doesn't really matter to me much, I want to run a coil on plug ignition system, staged injectors(550 primarys and 1000cc secondarys) plus have extra outputs and inputs for things like boost controller, water meth injection, etc. On top of the standalone I was wondering if anyone could give me a good suggestion for a water meth injection system and coil on plug system. Also I plan on using the factory cam and crank sensor in the distributor for synch just lock in the distributor at TDC. My future plans include high lift high duration cams (intake and exhaust staggered) shimless buckets, 1.5mm oversized intake valves, 1mm oversized exhaust, heavy springs and ceramic coated combustion chambers and exhaust runners. I also plan on 2 regulators for the fuel rails and a large fuel pump and possibly a twincharged setup with a gt40R turbo so I need something that can handle all of this and I was looking at AEM but all I kept reading about was issues like people going on their 3rd and 4th ignition in a year and waiting months to get one and failed water meth injection systems and tuning issues, etc I'm also not too favourable to an onboard MAP unless you can wire it to use an outboard style, thank you and sorry for the long post ]]> Stand-alone EMS mr2_mk1.5 http://www.mr2.com/forums/stand-alone-ems/Toyota-MR2-46495-standalone-opinion.html
