Jardon Posted June 9, 2011 Report Share Posted June 9, 2011 Thanks - that's useful. Some of my logging has been a VCT and the rest with the MTE Softloader. Neither is ideal for me - VCT is costly (but effective) and the Softloader is a bit limited in scope. Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted June 19, 2011 Author Report Share Posted June 19, 2011 So, last Thursday the car started breaking up under load, very soon after I filled the tank before taking a 100+ mile drive. Got progressively worse, AFR's got flaky @ idle, and it started breaking up closer & closer to atmospheric. I replaced the fuel filter & took a fuel sample, nothing evident. Swapped the OEM plugs for BKR&E's, and if anything it was worse with the colder plugs. Checked fuel pressure, cam timing, all hoses, etc. Put in Bosch FR7DC's, it seemed better. Car was 'chuggy', felt like it just lacked power, but at least it ran without breaking up. This morning I swapped the IPD HD coil packs for OEM, and the engine smoothed out immediately. Took it for a quick spin, and power is restored. The coils have only been in use for a month, since just before Carlisle - although I purchased them last July. Now I have to wonder how long they have been deteriorating - I've been pulling timing from the TT maps, when maybe it's been the coil packs all along. I'll have to try running an earlier map with more timing up top. While I had the cargo area all apart to do the sound insulation, I decided to check the voltage to the fuel pumps - at idle, 12.45v, when charging voltage @ battery is 13.68. x70's come prewired for CD changers, so I tapped the constant feed (fuse 16, 30a) which showed 13.5v with no load. I used it to power the pumps via 30a relay (J relay used for many things on our cars) I cut the existing power & used that to trigger the relay. Now I measure 12.95v with the car running. So, about .5V increase. I guess every bit helps to maintain flow. Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted June 20, 2011 Author Report Share Posted June 20, 2011 Installed the CoolingMist WI pump today. My old Shurflo pump was rated @ 150, but would typically drop to around 80. The new pump blew the pressure gauge off the line- it was only rated for 160psi. This pump is nice, it cycles the pressure, so you don't get the spikes at the solenoid repositioned the adjustable pressure switch to a more convenient location, and moved the PowerAire solenoid again. I'd like to reinstall a gauge, I'd like to know what the operating pressure actually is, regardless of the rating. Hopefully I'll have a chance to test it tomorrow.

dublin14 Posted June 20, 2011 Report Share Posted June 20, 2011 NIce! Lookin forward to seeing what it does for you. Quote Link to comment Share on other sites More sharing options...
Volvo5.0 Posted June 20, 2011 Report Share Posted June 20, 2011 That's the same pump that Devilsown uses (Aquatech DDP-5800). I'm curious to see how it works out for you as well. Seems to help my car, but my car is mild compared to yours :lol: Quote Link to comment Share on other sites More sharing options...

lookforjoe Posted June 21, 2011 Author Report Share Posted June 21, 2011 Did two pulls yesterday, after having to replace a dead coilpack. I've ordered a handy spark inducer tester (Calterm 66331), I borrowed one to check the coil packs, and found one of the Volvo ones had died. I also need to reinstall all the IPD coil packs & test them individually, I'm sure only one of them has died. For whatever reason, having one dead coil pack does not set a CEL for that cylinder Anyway, this is the comparison logs. I don't see any difference. This is with a .7mm nozzle using windshield washer mix. Still need to hook up the IAT for logging to see if the temps are actually changing post-WI injection. I have an .8mm nozzle I can also try. Car felt great on both pulls. Definitely too rich, but that is likely 'cos I've been compensating for a failing coilpack over the past couple of weeks. I need to go back & lean out the WOT sliders, and add more timing - my max timing in the upper load cells is between 7-10ºbtdc. Quote Link to comment Share on other sites More sharing options...

You may want to measure flow like Jardon did. He got 350cc after 1 minute using a 1mm aquamist nozzle (not sure of his pump pressure), which is about 5.5GPH. I haven't checked the flow on my DO5 nozzle, but it's rated from Devilsown at 7.07GPH @ 200psi. Your setup in theory would require more meth than mine. :unsure: Quote Link to comment Share on other sites More sharing options...

Yeah, I may need to break down & buy some actual meth, though the brand of solvent is a 50/50 water/methyl alcohol mix. I can do the flow/volume w/o too much trouble. I did a rough check yesterday, just to see what the atomization was like - much better than with the 100psi rated pump I had. Quote Link to comment Share on other sites More sharing options...
Captain Bondo Posted June 21, 2011 Report Share Posted June 21, 2011 It will read rich with the meth. Meth is fuel. I would buy methyl hydrate and mix your own, so you know you are getting a consistent ratio. Quote Link to comment Share on other sites More sharing options...

I would buy methyl hydrate and mix your own, so you know you are getting a consistent ratio. Sorry, I meant the tune was too rich overall, despite the WI. Between the two logs, there is no tangible difference in AFR or timing, so clearly I'm doing something wrong Thanks for the tip, I'll look locally for the Methyl Hydrate.

Captain Bondo Posted June 22, 2011 Report Share Posted June 22, 2011 If it's not noticeably richer spraying meth then it's not working. Or whatever wiper fluid you have doesn't have much meth in it. 1 Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted June 25, 2011 Author Report Share Posted June 25, 2011 Finally had time to make a support bracket for the LMA-3 - has to be within 3º of horizontal for the accelerometer to function. I used part of the SRS bolster bracket to support it. I wired the IAT sensor & hooked up the MAP sensor. Tomorrow I'll get the inj ground wired in & setup the LMA-3 in LM Programmer.

lookforjoe Posted July 1, 2011 Author Report Share Posted July 1, 2011 Well, getting the channels to display data correctly turned into a bit of an ordeal! The bottom line is that the channels need to be configured from the LMA-3 interface, before being configured in LM Programmer. Once I did that, I was able to get the IAT & MAP to display properly. Still may need to play with the IAT resistance/temp values. I boiled, froze & held the sensor in my hand to get three values to create a resistance/temp table. The highest accel value I have seen since hooking this up is about .6g. I'll have to do some hard pulls & see what I get. Injector duty is around 76% under full load, WOT, so that seems pretty much OK. I now have two MAP sensors, so I think I will use the LMA-3 MAP to record pressure on the exhaust side, then I can see what my EBR is like. EGT is not hooked up, I need to drill & tap the turbo exhaust housing to mount it. My gauge probe is just after the turbo. Quote Link to comment Share on other sites More sharing options...
Volvo5.0 Posted July 1, 2011 Report Share Posted July 1, 2011 Glad you got it all working. Getting the IAT readings accurate was definitely a challenge. I know I only have 9 gauges compared to your 12, but you need to work on the look of your "dashboard" .... Quote Link to comment Share on other sites More sharing options...
