Removed my sway bar years ago when I put the H&R bar on the back, sometimes I wonder if it would handle better with it on, but all and all I don't miss it, just my $.02.

Update: The root of the problem was a bad Innovative LC-1 wide band. Just got around to installing the new PLX system yesterday that I scored on ebay for about $100 a few weeks ago, what a difference. Started the car a/f solid as a rock at idle, looked at the vacuum gauge and it wasn't moving. Thought that I must have knocked the hose off of it, so I tap the gas pedal and it moved, car idled smooth :) Looking at the SD2 ver 1.1 chip on the bench and thought well, days going pretty well so might as well go for it, and more good news, car is back,  both Alky pumps are packed and ready for shipment tomorrow back to Julio, so the boost is turned down to 18, but after a couple of test runs, the tune is very close already, pretty sure that if I put that 95 psi alky pump back on, I could be back to 25 lbs boost, but it goes in the USPS system tomorrow, hope to see it back in about 3/4 weeks. Car does not go lean anymore, bad O2 system = bad input = bad output = crazy O2 readings?

Paul,
I ran a ground wire to the firewall, for the tests, (borrowed the one hooked to the wideband and scanmaster, made no difference) which is a ground kit from the block.


Under the dash is a nightmare, wires from the alkycontrol kit, scanmaster, wideband, knock sensor, A/F ratio gage, turbo/vacuum gage, it really needs a dedicated power and ground strip. Also been having issues with the wiper fuse socket for many years. Thinking I should find/buy a  new fuse block, or what ever that thing is called that holds all the fuses and redo it all. 


At this point I'm sure that the pump is bad, and possibly the controller, so now I have two pumps, one that leaks and puts out 65 and one that puts out 100 wired direct to the battery. I spent the extra money last year to buy a new pump thinking a new pump should give me another 3 years like the 1st one, well I got a year and a half out of it anyway.

Volts going in to the controller 12 volts, volts going out with the reastat turned to max (alky flow knob) 8.6 and alky flowing back into alky tank with pressure test kit. Next unhook pump from the system, 12.0 volts coming out of the control box with reastat maxed out. Next test, hook the pump up direct to the 12 volt battery, battery dropped to 11.7 volts, pump pressure = 100 psi.

Showing 8.65 volts at the box under the dash, the positive wire ohm's out but the negative wire doesn't, will look at it more tomorrow.

Just talked to Julio and he told me to check at the control box (the one under the dash) for 12 volts and check the ground and make sure the ground is not loose. He said the pump should be leaking if it's only putting out 85 psi. But I promised my better half to do stuff at her house this evening... I should get to it tomorrow.

It would be hard to get used to but, I may tune the car for 15/16 lbs and just run it with out alky.... see how long I can stand the lower h/p. At alky control dot com, pictures show over 250 psi.

Alky pump pushing 85 psi, Paul replaced a pump that was 135 psi and the new one tested at 165 psi.

Steve,


Have not checked the 1 to 1 with the new pump (need to do that), I have a alky pressure test kit, used it to test the pump when it was new last March, don't remember the value, may have it written down in the test kit box. Will check that tomorrow, may have to reach out to Julio to see what pressure I should be looking for. Will look at the chip next and see if I can turn off the wide band and run on speed density only.

Paul,

Never put the TR6 back on the car after the Ohio trip, have a new coil mounted to it and it's ready to go on, was keeping it as the spare, so I could try that.
When you say to verify the injector duty cycle is correct, I assume you want me to hook the laptop up to the power logger and check the duty cycle in the lean condition.
I will check the fuel injector connections, take them off and add some die electric to each connection.
Wouldn't surprise me though if it's the alky pump going south.... I'll update this post tomorrow, thanks again guys !!!

SuperSix, it rises good staying in the 11.0 A/F ratio range, then as the rpm's build into the 4500 or so the A/F drops to 14 and I get out of it, glance at the scanmaster recall and it shows 22.1  :icon_redface:

Steve,
Using wb to do chip correction, not sure if it's driving the chip, spraying alky, when it's at idle and I hit the test button the a/f dives into the single digits. I do have a gage I could put on the alky and check the pressure...

I have to run to a football game and watch my son in the marching band, I'll check the board later tonight and replace that fuel filter tomorrow with a puralator, keep the questions/comments coming...

Hi Guys,


Out of the blue I find myself seeing knock at WOT, in the past this has always told me it's time to replace the fuel pump. So 1st I replaced the filter with "Driveworks" fuel filter, as it was the only one in stock, still going lean in the gas. Checked the fuel pressure at the winshield while driving and had the 1 pound of fuel pressure for each pound of boost, now scratching my head and figure, well only one more thing to do... So next drop the tank and put a new Walbro pump in that I had new since the big Walbro incident a few yrs ago, where you sent in your defective s/n pump and they sent you a new one, guess what still have issue. Running the SD chip and it's showing the chip is trying to add the max fuel, so strange. Any ideas what might be going on? Going to replace the fuel filter again with a Puralator, but don't think that's it... Was thinking maybe the fuel regulator? Not sure....
