Fuel starvation issues may not be what they seem.
Written by White Spy
For the past while I have been fighting what appeared to be a fuel starvation issue on my '91 Miata.  This first manifested itself during autocross, where the car would stumble coming out of left handed sweepers but it eventually progressed to stumbling on all heavy acceleration.
 
I first changed out the fuel pump, because the symptoms could be corrected by running more than a half tank of gas, but that never cured the problem.  I then went on to changing out the fuel pressure regulator with the spare one that I had on my spare engine.  Again, this didn't cure the problem.
 
Each of these repairs helped somewhat, but the stumble was still there when accelerating hard.  I then started looking at related things, assuming that my friend Bob's suggestion of an electrical issue might be worth investigating.
 
I did the obvious and changed out the plugs and wires, given that I was running 3 year old wires, but again that didn't fix things.  I also swapped out my overclocked ECU for a stock one without getting anywhere.
 
This left me looking at the coil pack.  
 
Since I didn't want to buy a coil pack and igniter I decided I should test the coils and see how they looked.  In doing so, I found that my cheap Canadian Tire multimeter wasn't working, so I just pulled things apart and gave all the contacts a good sanding.  I figured that doing this would help make the time spent be worth something and I would get another multimeter from work to do testing later.
 
Anyway, cleaning the contacts for the wires between the igniter and the coil packs appears to have fixed things.  I can no longer get the car to stumble on hard lefts or on acceleration.  At least, my late night testing in SFU's B-Lot couldn't reproduce the problem.
 
So, the moral here is check the connection between your coil pack and igniter if your car appears to have a fuel delivery problem.  
 
Too bad I didn't guess to try this before I was at National Tour back in August...

An empty fuel tank isn't empty...
Written by White Spy
I should have written this last weekend, but I was sidetracked.  I'm now avoiding writing a paper that was due in mid-August, so I'll post this here.
 
I replaced my fuel pump last weekend with a Carter pump from Lordco.  Incidentally, that Carter pump is actually made by Walbro and is slightly larger than the stock pump.  I'm not sure what the lph on it are though...
 
Anyway, while doing the fuel pump replacement, I found out why we can usually autocross a Miata without problems with the fuel gauge reading below E.  The fuel gauge float sits out in the main chamber of the gas tank while the fuel pump sits down in a well that appears to be about as big as a 2l milk carton.  So, when the fuel gauge reads empty you will still have about half a gallon left.
 
Having done  the pump R&R, the car feels better and doesn't appear to starve anymore, so I guess I can go back to running the tank below E when racing.  Woohoo! 
 
Now I just need to check the plugs again and source out a set of 1.8l injectors...

Fun cocktail with double shot of danger.
Written by Kyubo

August 15, 2006 3:18AM Tuesday.

 Today I left Topless Chucky a msn msg and left for Horseshoe Bay. By the time I had reached Horseshoe Bay, It was already getting dark... and I wanted to drive fast. Knowing how potentially dangerous that road is (previous experience at our last miata meet for those of you who were there), I still wanted to despite the fact that it is a one lane road and there were plenty of cars, I passed on the opposite lane and just drove and drove possibly waaay above residential speed limit. It is not something I am proud of but it seems that the factor of danger is something that I risk in order to have fun. Now I wonder...  is it really worth risking it all? To my (still) adolescent and young mind... I believe so. To my mind... I want to try everything before I get any older. I cannot wait to hit up the track and test the real limits of my car.

 On a happier note, there was no tire screaming or smoking today. :)

Argh... The car is broken again...
Written by White Spy
Well, National Tour on this last weekend was educational.  Bruno placed 10th and I placed 12th out of 16 competitors.  It wasn't so surprising that we were stopmed on by the US drivers and their highly prepped cars but we should have done better relative to Jim, Bruce and Brian - car prep levels be damned. 
 
I think I get used to having 6 runs or more for figuring out the course, and when we have only 3 runs I can't get up to speed fast enough.  Oh well, I guess I need to learn to drive harder out of the gate...
 
We also had what felt like fuel starvation issues when taking hard left-hand sweepers, so I'm busy trying to work up a troubleshooting list.  The plugs are white and I had some temp. issues coming home from Washington, so we're thinking the symptoms point to fuel starvation.  I hope to get a few things diagnosed so that I can order the parts to do the repair this coming Saturday.  We have to have the car working again for the UBCSCC Team Enduro on Sunday.
 
Do cars ever stop breaking...?  Do Miatas ever have low cost parts? 
 
Man, I miss my Mustang and its parts costs...  :)

Got pwn3d by my mom...
Written by Beck

Okay, long story short.... I'm too depress to write. Today I found out my mom was wiping my car's hood with a wet towel beacuse she was "trying to wipe away the dust/dirt." Guess what? it's now full of trails of the wet towel...

Got Floyd's p.u.l.s.e DVD.
Written by Beck

This has nth to do with Miatas... but yeah, juz got their pulse concert dvd set. Oh man, it's so awesome! Gilmour's solos are full of emotions as always. It's bone-chilling juz to listen to it. Imagine also watching the recorded concert on tv... I was totally speechless throughout the songs and couldn't control my body from moving along with the music. Gawd, it's undescribable. It's an assault of all the senses (in a pleasant way). Maaaan, I wish you were here, haha...

Yeah! The car works again!
Written by White Spy

I have often heard that the most important mod. for autocrossing is tires and I finally have proof.  We spent the last few months questioning the setup of the car while running on older sets of V710s and V700s because we didn't want to cord new tires under braking, when the real problem was two fold: poor braking power and poor tires. 

While trying to work around the problem, I played with shock and alignment settings to keep the car driveable and, despite going off on a tangent that lead to the car diving on turn in and generally being slow, I discovered a couple of useful things.

I'm not sure I agree with the usual Miata alignment settings now, as I'm running camber numbers that are reversed front and rear and finding the car works well with them - especially now that the brake problems have been addressed and we have some decent tires on the car. 

Poor braking power has been addressed by swapping from the stock pads - which never really seemed to stop the car -  to some HP+s.  The car has been transformed and is feeling fast again. 

Now I just need to get some adjustable end links for the sway bars to help take out the slight right front lockup that occurs under braking...  Would it be inappropriate to buy some Maruha endlinks, or should I get the Racing Beat ones for a '99?

Speaking of Maruha, I'm reminded of something I ran across at the regional event that I was at.  It is funny listening to the talk going around in our local CSP class about the legality of other cars now that I'm not all that directly involved in this year's competition.  This becomes even funnier when some of the people complaining have run non-compliant cars in the past.  It's also funny to see competitors posting elsewhere about things they need to fix.  I guess that explains co-driving.  ;)

Oh yeah.  We just scrubbed in a set of brand new V710s for National Tour next weekend, so that should be a fun event.

Some issues
Written by Alex Harford

Right now I've noticed a few things that aren't working 100%:

  • Autoblog's main feed doesn't come up
  • Links to owner's galleries aren't working, and some people that already had accounts set up don't own them.
  • No classifieds yet.

Cooling off
Written by Alex Harford
So it's starting to cool off, and the weather forecast says it might rain this weekend.  I hope it's dry for the UBCSCC auto-x this weekend.  Unfortunately I won't be there, I'm still recovering from moving, only a few more boxes to unpack!
