My old labonte failsafe shorted out and I got a replacement.
I am running a do10 nozzle and on the old unit I use to get reading of 14-15

I got my replacement unit in today and I am getting a reading of 11-12. I ripped apart my entire meth kit and cleaned everything out. Tank, check valve, nozzle, pump, nothing, no kinks, no blockages of any sort. Put it back together 11-12 under boost. I unscrewed the nozzle and sprayed into a cup at idle I got a reading of 13 constant. With boost, I assume the pressure the nozzle has to overcome increases and meth pressure drop a little which is normal.

I later replaced the signal wire going from the unit to the the procede...11-12 under boost. I read somewhere that due to the voltages, some units may read higher than others, however there is another thing I notice. While at idle, or even if the car off, if i data log my meth value jumps around sometimes between 0-1, how is this even possible? I vertified flow, it flows as it should and my readings are still off by 3-4 points.

I had the same scenario happen when I changed out my controller also. Readings of flow dropped from consistent 14-15 to 11-12. Check out all my fittings and and still read low. Adjusted the number for progressive meth mapping. Have no idea what happened but after a week or two the readings are back up to 14-15. I think there had to be some minor obstruction in the fuel lines themselves and after a while it blew out. Now my logs consistently logs 14-15 flow rate on a M7 nozzle.

What about the 0-1 reading with the car not even on? no power to the pump as its activated by a boost switch.

Give Dan at Labonte a call. I had an issue with their solenoid and he took care of me right away.

[Clap135]

I am not running a solenoid.

[alextremo]

Sorry - just referencing an issue I had that was resolved quickly by Dan. I didn't mean to suggest you were having the same problem.

Yeah I logged it while idling and there is no such jump of 0-1 Clap did you see if the ground wire is good, I mean with my issue I redid my ground connection and it seemed to fix the problem and I am seeing full flow now...I log max at 15 with occasional spikes of 16 with a M7 nozzle..Wierd part is before I changed out my controller like you did, it was flowing perfect, then I changed out and flow immediately logged 11-12...SO i also rechecked everything because I thought flow issue...It wasnt until I wired in my nitrous ground and also redid the controller and failsafe ground at the same time that I finallyn saw meth flow go back to 15...Shiv told me that each controller has different variations of voltage, but I was not buying that would make such a difference in flow..

Clap135- You should see any flow voltage at idle. The next thing you should do is disconnect the flow signal wire to the Procede (to rule out the possibility of the Procede pulling up the voltage for some reason) and measure the signal with a voltmeter. See if it's really reading a positive voltage or not. If so, I would think it's a faulty sensor. But Dan at Labonte would probably be a better source of info than I.

Since we're on the topic of the labonte failsafe... have any of you had this issue:

I hooked everything up, set my injection mode to 12... no matter what (as in, the second i turn the car on) the procede is getting a flow signal (meth flow blinker lights are on). The issue doesn't make sense because i checked with a voltmeter and it reads 0... how could it possibly be getting a signal if it reads 0? could this be related to a faulty failsafe in any way?

[alextremo]

Yikes - does that mean you're transitioning to the more aggressive map without meth flow? I definitely don't think thats normal. If your voltage looks good with a voltmeter (0 with no flow, .5-.7 full flow) I'd say its a wiring issue or PROcede input issue.

Yeah JP...thats definitely not normal and I would troubleshoot it before even using the meth...I have not once encountered this issue and I would think its like others have stated wiring or defective safeinjection unit

The datalogging i've done so far has been without using a failsafe - just using one map with settings i'm comfortable with - just for testing (yeah yeah i know) but i haven't done that much testing so don't worry). This happened since the beginning when I first installed everything, it didn't happen randomly after.

Now that I have my car back from the injector BS, i want to figure out this issue. I know 100% the wiring is correct, it's impossible to mess up. Either the failsafe unit is busted or the XI has a different pin setup

[Clap135]

I went to the track today and wasted my entire day.
Flow has now dropped to about 3-4, which is IMPOSSIBLE.

When i unplug the hose from the nozzle I get something around 60, go through the check valve I get something like 52, go through the nozzle I get 4. The nozzle is not clogged, I must have taken that thing apart 3 times in the past 24 hours. I am going to rewire the entire thing and try again tomorrow, if its still acting up, im done with labonte.
There are no clogs. I am also going to test my boost switch with a bike pump and see if the pump is getting the proper voltage once the boost switch kicks on.

13.0@115 falling in and out of progressive mode. Thank I put in ms109, turned progressive off and set boost max to 20, this was stupid but I was angry.

1st gear 2.0 60
2nd gear, redline, sideways, inches from the wall, 3rd gear 20.2 psi and It hell 19 till the 3-4 shift which surprised me. Ended up trapping 110 lmao being that I almost wrecked my car. Then I went home angry

I meant for you to check the connections/crimps when I suggested wiring. I have an xi too, no different connections.

And even though there's only 2 wires, it's not impossible to mess up (believe me ) I found my issue by ghetto rigging a multimeter in the cabin to the flow wire and doing some pulls so I could see the voltage for full flow and no flow.

That seems off - I believe Debug byte 7 represents a percentage of the voltage of the flow sensor output. So no flow = 0v (0%), full flow = 5v (100%)

With no nozzle or valve I'd think you would be higher than 60% With the D07 people generally see ~13 which calculates to ~.6v

Would definitely be worth a shot to remove the flow wire from the PROcede and hook up a multimeter and check the voltage coming out of the failsafe the same way you measured the scenarios off the PROcede above. This will help further isolate the issue, as you can't be sure that the PROcede input isn't the problem.

I think my bran new failsafe is broken....AGAIN This thing is seriously crap. The first one lasted about 2-3 months before it shorted out, this one, never worked right.

What I did so far today:
Took out nozzle from bung. Manually pressurised the boost switch with a bike pump, 470ml/30 seconds at my pump settings of 250. Turned the car did the same thing, 490ml/30 seconds. So I am flowing roughly 980ml/min which is DEAD on to where it should be.
DO10 is rated at 14.14 Gallons per hour200psi
980ml/min is roughly .25 gallons per minutetimes 60 is 15 gallons per hour At 250 psi, the thing is spot on.
So I confirmed it to flow 100 percent the way it should be. Now to confirm the voltages, stay tuned

[Clap135]

It might be the procede?

If I unplug the signal wire from the labonte to the procede, the signal for debug byte 7 slowly rises and stops at 60? WTF If i connect the wire, it shoots down to 0 and sometimes goes to 1 and back to 0. Is the procede the problem?

I mean it's impossible to mess up in the sense that there is only one thing in the harness that you could possibly do the "update" to. and then since it's only a couple wires it's very easy to trace to see everything is in the right spot. I used a voltmeter at the back of the car near the unit and at the front as far up as I could and it reads 0

[alextremo]

Could be. Connect 1 lead of multimeter to the flow sensor wire and the other to ground. With D010 I think you should see .7 to .8 volts at full spray. If you do, its likely the Procede.

[Clap135]

Well I just read Shivs meth guid. I have no idea how you guys are getting 15-16 or how I was getting 15-16 readings before. 15-16 according to his guide is 1500-1600ml of meth per minute. That is impossible is a 10 size nozzle unless you multiple the pressure by 8 fold.

If my do10 is rated at roughly 650ml/min at 100psi, I flow 980ml/min at 250psi so it should flow 9.8 or slighly lower due to the pressure drop once actual boost hits and the meth pump has to over come that extra 15 or so psi of boost pressure.

[alextremo]

I'm not sure that documentation is accurate. IFS-30 documentation attached. If you're flowing 980 @ 250psi, IFS-30 output for flow sensor should be ~.98volts.

since the reading is proportional, .98v/5v = .196

Theoretically you should be seeing between 19-20 on the procede.

[Clap135]

Now you can log methanol flow! This is represented by Debug Byte 7 in your datalog menu. Methanol flow is displayed in units of 1000ml/min. So a logged value of 0.8 equals 800ml/min of methanol flow.

Taken from shivs forum. So I am flowing 980 so rougly .98 volts and the procede is giving me a reading of 11 now for some reason.

Either way I wish I could contact shiv about these procede readings with no signal hooked up
Anybody got his cell phone while i got the car apart? I don't feel like putting it back to gether only to find out the procede is screwy and I need to send it out.
