OK well me and my cousin were putting in the Axpei Power FC and a boost gauge today. After putting in the Power FC we went to teh boost gauge. When we got done working on that we turned the key over so that the radio and lights and everything would come on. We left them on for a while and finished up the boost gauge. Right before cleaning up we start to smell gas really bad. We look under the car and gas is leaking from where the turbo meets the intake pipe. We removed the intake pipe and looked ofr a leak nothing. We turned the key back over to find out if we coudl hear or see the leak. After leaving the power turned on a minute gas started powering out the intake! Yes where the intake goes into the turbo it was coming from there.

I have pretty much narrowed it down to the Power FC either being programmed wrong or something but the injectors are proly stuck full open and pumping gas through the whole system. We took a compressor and blew a ton of air down the intake into the turbo and it kicked a half gallon of gas out the lower intake. We pretty much figured it went through the entire car and is dry rotting the seals. We drained the oil and their was NO GAS in the oil so I think we are somewhat safe there.


My question to you guys in why in the world would this happen?

How would gas get from the injectors into the turbos?

What potential damage am I looking at?

Woudl not doing the Apexi Power FC wire mods make this happen?

What should I do now?

Please help me anything you guys can tell me would help. I jsut got this car and it was freaky spotless before this. Please help me guys I am tottaly new to this car. Help!

 

i just dont understand how you wired it wrong. it plugs right into your ECM harness... did you do the boost controller with the FD for the PFC? obviously your injectors work, maybe you are not getting spark?

 

No I never turned the car over. I hoenstly plugged in the ECU and then started workign ont he boost gauge. I never tried to start the car the entire time. I just turned the key so that the lights and radio and everything would switch on. The PFC was makign it pump gas while the engine wasn't turned on. I have no idea why it did this but will the gas get in the engine and dry root those seals? Gah I am so scared right now

 

It would seem that for some reason the pfc is telling the injectors to open or possibly prime the system but it's not stopping so it just keeps pooring gas in. Probably leaking out of the exhaust ports and through the turbos.

I'd just pop the stock ecu back in turn the ignition to on and see if the fuel comes out. If not pull the plugs and let it dry for day or so then get a fire extinquisher and fire it up lol.

 

Unflood your engine and start again. Your seal will not waist away they are metal, but you can lose compression if it is severly flooded.

Your fuel pump is going to turn on any time you turn you key to the on postion. That has nothing to do with the PFC.

If I was you I would read up on the PFC and how to tune it or take the car to A-spec I have had them tune my car and they did a great job.

 

The install sheet told me to cut like 3 wires and splice one together. I never did that because the car had a piggy back ecu on it and it looked as if it had already been done. Coudl this be the problem?

 

that would be a most probable cause. was your PFC brand new, right out of the box? if so, it should be tuned for a stock FD.

 

No, the three cut wires are for emissions. The car should still start up whether they are cut or not. I agree that it's time to put back in the stock ecu and unflood the car. Where did you get the pfc from?

 

r0t0rhead is owns www.rotorsportsracing.com

He said it was his former customers PFC and they hardly used it. How do I unflood the car? How do I know that no gas got into the engine? How long should I wait before trying to start the car? Is there anywhere I should check for gas? Could I have cuased damage to anything?

 

Geesh, that sounds like an FD problems for ya : ). I gotta quick minute so... to unflood ur car u gotta try and start the car normally..crank for about 6-10 sec. Then crank with the gas pedal down for 6-10 sec.

Ur gonna need new spark plugs most likely. Good luck. I'll send ya a pm with my number, lemme know how things go.

 

What kind of spark plugs do you guys suggest?

 

NGK BUR9EQ Trailing
NGK BUR7EQ Lead

If you want Platinum plugs, it's the same name with a "P" at the end of each.

This is the stock set up.

 

That PFC might have a different map on it. I would se what map is on it and reload the one its supposed to come with, that might be a few of the problems

 

What is the process to unflood the car? How long do I wait before trying to start the car again

 

ok, before you deflood your engine. please humor me on something. i have a gut feeling that you are not getting spark.

1. pop your hood
2. find the fuse panel connected to the positive battery terminal
3. the very middle fuse, the EFI, you remove that

then verify that you have spark...

1. take out a spark plug
2. put the wire on the removed spark plug
3. make sure the plug is on your chassis to ground it out
4. have someone crank the car and make sure you are holding the plug wire and not the plug
5. verify that you have spark

well, since there was fuel pouring out of your turbos... you are kinda screwed. that engine is severly flooded. but, to unflood, you need to put back in the spark plug and...

1. pop your hood
2. find the fuse panel connected to the positive battery terminal
3. the very middle fuse, the EFI, you remove that
4. start cranking the car for 15 second spurts... and do that 3 times over while pumping the gas pedal
5. put the fuse back in
6. start the car
7. leave it idle for about 5 minutes

NOTE - the exhaust will bellow out smoke like a motherfucking chimney, do not stop the car when you get alarmed and see that because you will only flood the engine even more!

 

This must be your first rotary powered car if you don't yet know to unflood it.

 

people start somewhere. at least he is asking questions looking for help about tuning and not asking about gay ebay lights HAHA

 

no matter how long you wait, it will always be flooded. a piston engine you can wait a little, a rotary is different.

 

Best way to unflood is by holding the accelerator pedal to the floor and cranking for 15 - 20 seconds or so. By holding the pedal to the metal, you shut the fuel off (well...at least with a stock ECU anyway, as that is how it is mapped...) to the injectors. The engine will sound really weird, making a sort of wimpy whiny whirring noise. So turn it over like this, pedal to the floor. Stop. Take your foot off the gas. Crank it again for 15 - 20 seconds. Repeat this until the engine starts. You may run your battery down, so be prepared to have a fresh battery or a charger handy.
I have to agree with everyone else....there is something wacky about that PFC.

 

um DO NOT TRY TO CRANK the engine over as every one is telling you to. If you have filled the engine with enough fuel to poor out of the turbo's then There is a very good possibility that you will hydrolic (spl?) the damn thing as you cannot compress a full chamber of fuel, I had an inj. get stuck open over night on a piston motor and the next morning not realizing this had happenned I tried to crank it and ended up w a shatterred piston and a bent rod pull the spark plugs and turn the motor over by hand a few times you may also want to pull the turbos back from the motor to try to emtpty the exhaust manifold.

 

Hey guys thanks for all the help I really appriciate it. I was able to unflood the car. I took the old Spark plugs out which weren't really that bad because i never tried to crank the engine. Either way I poured about a gallon and a half out of my intercooler and then another gallon out of my intakes and IC piping. Once I pulled out the ignition and fuel pump fuses I cranked it about 7 times and got all that gas out of the system. After I jumped the car it started up perfect. I let it sit there and smoke for about 15 minutes and after that it was ready to rock. Thanks again for all yoru help!

 

Im pretty sure you can't hydraulic a 2-stroke.

 

^ LOL ah pretty sure no wait positive! a rotary still compress's the intake charge which in this case would be liquid considering he filled the intake manifold. not to mention that all of the exhaust is most likely filled with gas also so your sitting on a bomb...
