what resistor should i use to delete the precontrol and waste gate solenoids

Im doing damians perfect pattern boost controller and i cut the connectors of since i simplified the harness, i was going to use the resistors that rotary resurrection uses for the emissions delete or would you guys recommend something else

ok, if you want to do it right, you'd really want to pull the engine harness and depin the wires from the connectors to the ECU. If you're running a PFC, then you wouldn't need any resistors for any of the emissions garbage because the PFC doesn't care about any of that stuff.

I would recommend not doing this on the stock ECU. If you don't have a PFC (or equivalent upgrade), wait until you do.

Also, the stock ECU needs the precontrol and wastegate solenoids to run in sequential. if you delete them and upgrade to another type of boost control, in order for the stock ECU to use them (which I doubt it would be able to) you would have to still run new wires back to the ECU for it to run them.

I guess I don't understand why you think you would need resistors for the precontrol and wastegate solenoids. If you're running sequential, either the stock ECU or the PFC would need them.

Are you fitting a boost controller? If you were fitting a boost controller to replace the functionality of the wastegate and precontrol solenoids then yes you can fit resistors in the place of the solenoids to fool the stock ecu into not throwing a code.

Turning up the boost on your car so you can blow it sky high and add your car to the list of blown engines, and yourself to the list of "rotary is unreliable, gotta getz ls-engine"-guys?? Sorry if i come over as abit harsh, but there is enough of guys turning up boost like idiots.

One small thing:
I am not, under any circumstance calling you an idiot.


I hope you have the mods to support this.

If not, for perfect solenoids, take two of these and call me in the morning.

Or, dont call me, fit em and enjoy perfect sequential control, if all your other stuff is up to date offc.

Its clear the above posters don't understand what you are doing.

I don't know that the stock ecu will throw a code if you don't have resistors in place of the wastegate and precontrol solenoids coil like they do for emissions solenoids, but adding the same resistors sold for emissions solenoid removal will certainly not hurt anything as a just in case.

I'm running the dual hallman pro-rx instead of wastegate and precontrol and its really an awesome set up for perfect boost pattern/transition.

OFC I just left the wastegate and precontrol solenoids wired in with no boost lines to them for the stock look, but I can see you are going for a clean simple look with sequential turbo operation.

ok thanks for the advice i dont see what my post have to do with any supporting mods for damians perfect pattern. it can be done to all rotaries. theres no mods needed to support this except using resistors or keeping the solenoids

thats what i want^^^^

i talk to damian and he said to use resistors so the ecm doesnt through a code, i did deleted the connector and removed the solenoids to clean up my engine

A range of values will work for the resistors. A couple that I have used are:

330 ohms, 1 watt (min)

1000 ohm (1k ohm), 1/2watt (min)

I have stock ECU and dual Hallman MBC, no code. But I'm not getting any code for all the emission stuff I removed either, so I don't know.

The wastegate control and pre-control will NOT throw codes or put you in limp mode. No need to worry.

Makes sense...they are strictly for turbo operation. Nothing that would need a CEL


for the record, I run the hallmans with the solenoids capped off. Easy Peezy.

tt7hvn, check this out

the 'outflow' from the actuator is unnecessary if the controller sends the proper amount of inflow, which hallmans do.

Just to clarify, you are not getting a CEL. Not every code triggers the CEL, so you are likely storing codes being thrown from the emissions equipment delete, but it's not triggering the CEL.

Ahh ok, I think I'm too used to the OBDII stuff where a single code will throw the CEL.

very, very,very good to know!


glad these OBDI bluetooth inspectors are ~12 bucks
