1jz (non vvti) sc400 swap, won't start?

hi, i have a novice knowledge of tuning as i have daily driven/tuned my nissan rb 20/25's for years. so this aem relm is new for me, the wizard this and the wizard that thing is kinda new to me, but i would like to learn the curve.

 

i brought a 1jz v2 box from aaron at driftmotion over a year ago. i just now have the time to actually sit down and get this going. before when i got it i pluggged it in and tried to crank the car, and no start. i adjusted the tps table and still no dice. it is/was loaded with the stock basemap for a 1jz.

 

it's not the car or engine because i daily drive the 1jz-sc400 now on the stock/jdm engine without a hickup. it starts in the cold,warmth etc so that can't be it. ive asked aaron for assistance but he is a busy guy, so iam wondering if there any jedi's on here with experience with the 1jz(non vvti) boxes? apparently these are 2 honda boxes modified for toyota application, running high inped injectors just like the stock 1jz does. here is a list of my mods.

 

-stock block 1jz(non vvti) jdm so runs on map sensor

-3" catless exhaust

-holset hx35/40 turbo (single conversion)

-areomotive fpr

-innovate wideband

-3" front mount intercooler

 

so pretty much just nare bones now, nothing serious/crazy

call where u get your ecu

call where u get your ecu from, it is a custom application and it should be solved with the guy who sell this product to u.

 

just because it plug into your harness doesnt mean it should run.  when u do a swap, so many thing could be changed, for example, ignition could be either group or sqential firing, do you know if your box have the right program? or how do the guy who sell you the box magically know what setup/swap you are runing? do you know what your box support to work under what setup?  

so i guess it is easier for u to call the guy who sell you the box and tell him what is your setup and have him send u a config that would match your setup.

well i finally got it squared

well i finally got it squared away. again, iam a newb when it comes to aem(used to nistune) the syncing of the timing was easier than sex. the box and initial basemap was/is correct, now i just have to adjust my afr as it's super rich at idle(10 afr).
