MOP problems (help)
#1
I recently purchased a 1990 rx7 convertible, my first rotary.
Heres my problem, the ecu is throwing codes 26 & 27 (MOP issues). Its my understanding the S5 MOP is extremely expensive.
What would be necessary to delete the MOP (for premix)?
What I've figured so far
-Pipe plugs for rotor housing
-ECU Mod to prevent it from going into limp mode from lack of MOP signal
-another ECU (if mine is fried)
What would be necessary to run a mechanical MOP?
What I've figured so far
-Mechanical MOP
-ECU mod to keep it from going into limp mode from lack of MOP signal
-a good ECU (if mines fried)
Am I missing anything?
Which would be more cost effective (short term, and long term)?

i am currently running a s5 hybrid engine ( in an s4 ) [ with LPG mixer and dizzy = no ECU ]
and i have fitted the s4 timing cover,, turbo oil drain and TB ( and use a cable for the linkage )
all these parts are necessary
though if clever you can mod the s5 TB for a linkage
and use a cut shut oil drain with hose ( ala 12a timing cover swaps )
BTW,, mines coming off this week to refit the EOMP
as i have a standalone controller for it that i helped develop
( runs off a 5V load source,, be it TPS, map or aftermarket ECU aux out )

oh,, and PS,, the s5 water pump housing may need a small grind at the back to make it work with the s4 timing cover
- i find this pump clashes with at least 12a timing covers ,, and this may well include the s4 one
( as i have swapped s4 and 12a pumps irrespective of cover )

Sounds like converting to premix will be the most cost effective method to solving this problem.
So if I understand correctly, in order to switch to premix on a S5 13b, I need:
A blockoff plate

Oil metering injection bung plugs

ECU mod for MOP removal

Update: Discovered calcium deposits / water stains inside the ECU casing on the curcuit boards when inspecting it for damage. Going to get another ECU and see if its just my ECU thats damaged.
Is there any reason I cant use a non-convertible ECU in my vert?

Cool, I'm down by tampa bay so I can probably make a drive up there to pick it up, if you can find it.
How much would you want for it?
when it rained today I discovered the source of the water damage is a damaged convertible top seal, and door frame seal (both by the window's front corner).
Sealed it up with some home depot weatherstripping for now. I should have it minimized to a drip now. Going to vacuum out the water, and start leaving towels on the passenger side just in case it leaks more than I expect.
Considering attempting to relocate the ECU higher to avoid waterdamage, or sealing the casing with neoprene that I use for roofing.
Any thoughts?

checked MOP. Half the connector isn't reading anything. If I had to guess, probably a bad solder joint somewhere. Guess I'm gonna get to see the guts of the MOP this weekend to find out where I'm losing current....... Dont try this at home kids.
