which would you rather have and why? reason i ask is i happen to have a 1900 laying around but was hesitant to use it as the additional wiring to the body and trans vs the PNP of the 1800 with VIRTUALLY the same ability.

but as time goes on and the more i learn and add to the build its just looking more and more like ill be using the 1900 over the 1800 if i can find one or the PFC i currently have installed and running.

also i only know of one person actually running it on a rotary and thats ernieT but he dosent work his car and not much info so id bepulling help from both aempower and here if i do this and if needed.

anybody thought about using one or just sticking with the PNP 1800 unit? my engine harness is about 3000miles on it so new but i think someone else can get better use ut of it that dosnt want all the additionals i do. the PFC is great for what it is but any more than stock style systems it just kinda lacks and is a compromise in my opinion. besides i think selling the PFC, commander, datalogit, eng harness, fast IAT sensor, pnp 3bar map sensor and twin power will all but fund a couple hundred of the conversion to full blown AEM 1900u universal standalone ECU wiring sensors and m&w ign.


so any thoughts?

I've got a 1800 installed in my RX-7, with a couple of simple modifications to the stock wiring harness (removed some un-used connectors, ran new wires for injectors and a fuel pressure sensor). Toughest thing about doing this was removing the stock harness, unwrapping everything, then wrapping it back up again to look nice again. Adding the wires wasn't too bad, especially if you get new pins for the ECU connector and crimp them to the new wires instead of splicing a new wire to an old wire.


I also helped a friend install a 1900 in a Miata, he used the long AEM harness (the one that includes fuse & relay panel and about 5-6 foot wire lengths for each input or output). By far the most difficult thing was connecting to any OEM sensor that we didn't have new pins for. You've got to either splice a new wire to the old wire (butt connectors, or solder) or get fancy and solder the new wire to the OEM pin which takes forever and is not easy. This doesn't sound too bad, but think how many OEM sensors you'll be retaining: on the Miata it was cam sensor, crank sensor, ignition coil pack, coolant sensor, throttle position sensor, knock sensor, and I realize this doesn't sound like much but there are multiple pins each and that feels like a lot of splicing if you do it all at once. Crimping new pins onto new aftermarket stuff was pretty easy in comparison... IAT, MAP, injectors, etc...
Also it took a while to connect to the stock tacho and vehicle speed sensor to make them work, not necessary because the PnP has that stuff already done for you.

The pre-start setup took longer with the 1900, but it was nice that it didn't require inline resistors for the low-impedance injectors he used.


The 1900 does have lots more spare 0-5V inputs... the 1800 has lots of outputs for driving the turbo control solenoids, not as many spare 0-5V inputs if you want to datalog spare pressure or temperature sensor voltages.

If you decide otherwise on the 1900, PM me. I'd like to have it.

ah missed your guys post on this thanks....

scotty ya i understand the added cut/splice of the 1900 but in my postition the only thing i honestly plan on keeping stock is the crank triggers but even those im looking for a better trigger and setup as its easier to get aftermarket new plugs than desent oems to splice. not to mention AEM has settings for thier sensors more so than oem cut/slpiced ones. not to mention the tech on the oem stuff is just OLD there is newer faster sensors all over now i want to use em. AIT sensor for example is extremely SLOW.

so as far as wiring to the engine not a big deal to me setup ya it may take a bt more but i havent looked into the TRANS and DASH connections from the stock harness and if theres anything im going to run into conflicts with especially since the trans plugs are all on the stoc engine harness as well.

hwnd- ill keep you in mind although i have a FS in the race section if your interested honestly id still like the 1800 as my harness is new and already ran and would be faster to get rolling currently and it has everything i need as i will be using inj dynamics inj and i can easily add 2 extra inj and 1 ign with the wires not used from the solenoids now as well as for the boost controler this pretty much covers everything i want so hit me up if yu really want it.

AEM sells plug and pin kits for all of the ECUs they sell. this means you can buy a male 1900 plug and an 1800 receptacle. all you will have to do is mate them yourself. with the way they have AEM Pro all you have to do is select all of the FD sensors(AIR, H2O, REF/SYNC, ect..) and you are good to go. then get a base map from someone and tune away.

yes iv looked into that as well no real decision yet on exactly what i want to do.
