HFS-3 was working... now a hiccup ::FIXED::

[gengo]

I had my HFS-3 system installed on my Evo X and got the car tuned on March 15. Everything was pretty rosy, and the car put down some great numbers. I'm running 50/50 with high quality meth .

The pump was a bit louder than I expected (sounded like electrical sparking whenever pump was triggered) but I have no previous experience with water/meth injection. I guess this sound is normal. Just sharing this for others.

On my first long test drive (spirited driving in Malibu), I got about 30 minutes in before I got a check engine light for my wastegate solenoid. Took car to tuner/installer yesterday because the car was down on power. Initial diagnosis is that the system is only spraying intermittently. Had to switch back to a 91 octane safe map.

Has anyone else experienced this issue or have ideas on what to check first?

Cheers in advance.

can you post some pictures of the tank and pump location? I am suspecting air has gone into the system. It should be picked up by the failsafe.

[gengo]

Sure... will snap a pic and post it!

[Richard L]

Can you clip a jet on your screen put the jumper link on "M.TEST/SYS" and describe the spray pattern to me. Also oberve the bargraph on the gauge.

Hope these pics help!

Since I don't work on the system directly myself (lack of garage and tools), I have to wait until April 10th to get my car back to my installer. They will go back through all the install steps to diagnose the problem.

[Richard L]

Can you pm me their phone number to I can be on stand-by on that day. Alternatively they can email me to request a call from me.

Richard, you got PM.

[Richard L]

Thank your for contact details.

Can we try to make an attempt between to solve this problem. I can call you on the phone and do some quick diagnostic work. It is not necessary to have a garage, you don't enen have to drive the car. Just need a quiet road.

[gengo]

I'm willing to do some diagnostic work... sure. I'll PM you my number as well.

[tank]

where did you get install done? I am in Agoura Hills.

[gengo]

Installed by HBspeed.

I finally have time to take the car back in this Saturday to see if they can get the system up and running properly.

[Richard L]

Please keep me posted

[gengo]

System working as normal! :D

When I reinstalled my rear seats after my first install, I pinched a line. The pinch was severely limiting flow. I got the crushed section of line replaced and rerouted. Good to go!

[Richard L]

I would never have found this! Thanks for the update.

Hi,
I'm running into the same problem too. I'm getting a CEL for my wastegate solenoid, but I couldn't really say if I'm down on power as I've been only able to get one good pull on the road before getting the CEL. I'm planning on bringing it back to the installer in a couple of days to try to diagnose the problem. I was wondering if anyone knows what I can do in the meantime to try to isolate any problem. The only thing I've tried so far is turning the WL potentiometer on the gauge all the way counter clockwise, but I'm still getting the same thing. Any help is greatly appreciated. :(

[Richard L]

Who is your installer?

Ir sounded like the failsafe is not wired or configured properly.

[jdqkr2]

Hi Richard,
I had the HFS-3 installed by the folks at WORKS in CA. They've done a lot of good quality work to my car so far. I'm thinking of just going through all the preinstallation tests again and double check all the wire and hose connections when I bring the car back to them. I believe the boost wire was "cut and spliced" to the brown and white wire going back to the controller box so the car would run at wastegate pressure upon failsafe activation. With the injection kit turned off at the gauge button, would I get a CEL or does the controllers "Anti-CEL" option prevent the CEL?

[Richard L]

On the HFS-3. There is a option to prevent CEL. All you need to do is link up the jumper link to DR="1".

When DR (dummy resistor) is linked, it immulates the load of BCV (boost control valve) so that the ECU can not see the boost vakve is being cut upon failsafe activation.

Make sure the brown wire goes to the BCV and the white wire goes to the ECU after the OE wire is cut.

Works is a great company Pete is very careful but he needs time to get to know the system.

[jdqkr2]

I'll double check that CEL link on the controller. I just spoke with Pete, he noticed at partial or WOT the yellow light or low level light on the guage would go on and the car felt like boost just dropped to wastegate pressure for a few seconds then the yellow light would go off. Also, I've noticed when I clear the CEL and run the car afterwards the CEL doesn't go on. But the second time I start up the car the CEL light comes back on and I get the same error code. I'm guessing at this point I'll need to check the "cut and splicing" of the boost line going to the ECU and check the spray pattern of the fluid lines.

[Richard L]

Can you yell me how many bars are you reading on the gauge at WOT?

Aslo the settings (face of a clock)

- SC...... 12 o'clock?
- WL ......?
- WH ......?

[jdqkr2]

On 2nd and 3rd gear at WOT the gauge is reading around 4-5 bars consistently. On 4th and 5th gear the bars keep going up and down from 0 to 3 or 4 bars back and forth. I noticed on the 4th and 5th gear pulls, power felt like it was slowly dropping from say 4000-5000 rpms on up. Right now the gauge settings are:
SC-around 3-4 o'clock position
WL-~9 o'clock
WH-~3 o'clock

I just met with Pete yesterday and he double checked all the wiring connections and jumper links (DR=1)and everything looked ok. We observed that after we cleared the CEL and started up the car there was no CEL light. But when we shut the car off for ~10 seconds then start it up again the CEL light would come back on. The OBD2 code reader displayed I'm still getting a P0243 wastegate solenoid error at around ~500 rpms upon start up. This is with the kit both enabled or disabled at the gauge button prior to starting up the car. We didn't have a multimeter to measure the resistance in the boost wires between ECU, HFS-3 controller and BCV to check if the signal was being interrupted somewhere in between. Any thoughts?

[Richard L]

1. It appeared that you are not runnign that many jets as the SC is turned up quite a bit. Let me know how many jets you are running.

2. Is the DR= "1" linked at the CEL jumper link?

3. This interesting CEL. On aniothe jumper link "DHB". you can disbale the failfail when the gauge is on the off position.

4. Check the grey connector/ECU splice, the brown wire to the BCV side and the white wire to the ECU side. DR= "1"

"1. It appeared that you are not runnign that many jets as the SC is turned up quite a bit. Let me know how many jets you are running."

I'm running one jet.

"2. Is the DR= "1" linked at the CEL jumper link?"

DR="1" was set during the original installation and still is set.

"3. This interesting CEL. On aniothe jumper link "DHB". you can disbale the failfail when the gauge is on the off position. "

I removed the "DHB" link, cleared the CEL and still getting the P0243 during the ~500 rpm starting.

"4. Check the grey connector/ECU splice, the brown wire to the BCV side and the white wire to the ECU side. DR= "1" "

Pete double checked these wires.

It looks like the primary issue is the P0243 CEL I get just by starting the car in the parking lot without even moving the vehicle. The other issue regarding power dropping at 4th and 5th gear and the gauge displaying 0 to 3 or 4 bars back and forth may be a side effect of this P0243 CEL. What do you think?

[Richard L]

Can you tell me how many jets are you running?

Based on your SC setting of 3-4 o'clock, the reading will be quite abbrupt due to the lesser resolution as the SC sensitivity is increased. The HFS-xx is optimized for running two jets. I can easier reflast the flow table to make the flow reading more stable.

[jdqkr2]

I'm running one jet.

I can see how my SC setting may be affecting the failsafe window when the HFS-3 kit is injecting and the car is in motion. I think my main issue is the wastegate solenoid CEL I'm getting every time I start the car without moving the car. Is it possible the boost signal maybe severed or interrupted somewhere between the BCV, HFS-3 controller and/or ECU? Since I've already tried unlinking the "DHB" jumper to bypass the failsafe feature, is there a way to check if the controller board is blocking the signal?

[Richard L]

With the DHB un-linked, the gauge switched off and DR=1 (jumper link), there is no way the system interrupting the signal between the ECU and boost valve. Can you confirm the wiring (brown and white) wire of grey connector is wired correctly. Brown on the BCV side and White on the ECU side (after cut and spliced).

Can you tell me what model of car do you have?

[jdqkr2]

I'll get with Pete to check the wires and probably hook up a multimeter to check the connection points.

Sorry about that, the HFS-3 was installed on my 06 Evo 9.
