AEM is ghey... its a cheap rip-off of the Pro-EFI system that has been around for YEARS... and is better than the AEM-version of it.
I had a friend who put a Built H22A into his 99 Accord 5speed w/ a 60-1 T3/T4... it took him FOREVER to install it... and 2 hours to just toggle the fuel pump on and OFF... yea... AEM is better
If youre going thru all the Hassle... you should run a Hondata if you have a Honda... its tried and true. why try to reinvent the wheel and one-up the next guy. go with what works, trust me.
and you can get a DIY-WB02... a full Laboratory-grade UEGO Wideband setup for ~$450, including a LED Numerical Display (think, huge calculator screen w/ Red numbers) and it reads into the tenths... 13.8:1 ?
