Adjustable timing lights are not accurate when used with the waste spark ignition system on DSMs. The adjustable timing light must be set to zero and the 5 degree mark on the timing cover is used. This will be difficult to do without a timing cover.
Without a log it's hard to tell but the only thing I can think of is the lack of a "keystroke" signal. Without this signal, "crankingfueladj" will not work. The "keystroke" signal is 12 volts from starter relay to ECU pin #108 on a 1G or pin # 71 on a 2G only while the engine is cranking...
If it's not the clutch position switch or the starter relay under the dash there is 1 wire connector between the starter harness and the main harness. it's located behind and below the thermostat housing. THis wire carries the start signal from the starter relay to the starter. Make sure it's...
This sounds like you're getting a P0300 "random misfire" code. Your profile says that this is a 6-bolt swap with ECMLink.
Try unchecking the "Cylinder Misfire" box on the Misc tab in ECMLink.With a 6-bolt swap, you have to use a 1G CAS. The 1G CAS is not compatible the 2G ECU's misfire...
The ECT light has nothing to do with starting the engine, There are two sensors on the thermostat housing. The 2-wire sensor tells the ECU what the engine temp is. This can affect starting. The 1-wire sensor controls the light. This light will turn on when the key is switched to ON (as a bulb...
A very basic test of the ECU is to turn the key to ON and observe the check engine light and the factory boost gauge. The check engine light should come on and stay on for around 5 seconds and then turn off. The factory boost gauge should go up to approximately 1/2 scale and stay there. A...
Actually, the wideband does measure fuel too. At any AFR richer than stoich there is no longer any oxygen in the exhaust to measure.
Kevin Jewer explains this very well on his website.https://www.sixsigmatuning.com/pages/general-wideband-o2-sensor-infoJim
The stock oil feed line for the T25 comes in 2 pieces. The fitting that goes into the oil filter housing contains an 0.070" restrictor which must be used.

Actually, this is fairly normal for a 2G. The 2G ECU will adjust voltage as needed to keep the battery charged. When the car is first started, the alternator will charge at 14.3 - 14.5 volts to replace the current lost during the engine start. As the battery comes up to full charge, the voltage...
This sounds like a blown sensor ground in the ECU but it could also be a broken sensor ground wire (black wire) to ECU pin #92.

You would want a dynamic seal. A carbon seal is only needed on a draw-through carburetor set up. I would think that the 360 degree thrust bearing is overkill for the T25. I would stick with the 270 degree thrust bearing.
Adjustable timing lights are NOT accurate when used with the waste spark ignition system on DSM's. An adjustable timing light must be set to "zero" when setting the timing and the 5 degree mark on the balancer is used.
The waste spark ignition system cuts the time between firing events in half...
Actually, your tuner is correct. ECMLink CANNOT adjust boost based on the flex-fuel sensor.

If the engine misfires due to a spark related issue, the wideband will read lean. The unburned oxygen in the exhaust, from the misfire, will cause a lean spike on the wideband. The fact that your Power Transistor is getting hot would be a red flag for me.Jim

Has anyone tried chamfering the head bolt holes in the block. When the head is torqued down, the threads in the block exert enough pressure to distort the cast iron around the bolt holes and raise it slightly. This can lower the clamping force and lead to the head gasket leaking...
If your #1 piston was really at TDC when you took those pics, your cams are definitely out of time. Your exhaust cam is advanced 1 tooth and your intake cam is retarded 1 tooth. The timing marks have to line up with each other but they also have to line up with the top of the head or a straight...

Get the BPR6ES plugs. Do not get the BPR6ES-11 plugs. The BPR6ES-11 plugs are gapped at 1.1mm (0.044"). The BPR6ES plugs are gapped at 0.032". These should be re-gapped to no more than 0.028".Jim

You have to add it to your Captured Values and Displayed Values.Pull up a log and click "edit" in the top left corner and click on Captured Values. You must be connected to the car to do this. After you add ISCPosition to your Captured Values you can add it to your Displayed Values.Jim
With ECMLink, DO NOT ground the diagnostic or timing pins, either with a jumper wire or with the checkboxes in ECMLink, when setting the ISCPosition.Set your desired idle speed on the RPM/TPS tab. Make sure that your idle switch is working (it should read "1" at idle). The ECU will not try to...
I just got onto Facebook (but still don't have my own account there) and noticed all the problems you're having. I'm sure this is a balance problem. Your compressor wheel is probably just single plane balanced. I don't know what the electric motor company does about balancing. You should look...
FPR overrun only occurs at idle. Some AFPRs are available with replaceable, different sized return orifices (AEM for one). I wouldn't worry too much about overrun unless you are maxing out your fuel trims.No need to postpone your WOT tuning. Just start off with very low boost and keep a sharp...
Your cruise logs look pretty good. Your fuel trims are good.You're still overrunning your FPR. The fuel pressure only dropping to 35 psi, with the engine running, shows this. It should be dropping to around 29-30 psi, depending on your engine vacuum at idle. For example, if your idle vacuum is...
OK, those logs do look good.PTE 1000cc injectors are the same Delphi injectors as FIC 950cc injectors. PTE just rates them at 50 psi base fuel pressure while FIC rates them at 43.5 psi fuel pressure.The fact that you had to lean out your Global and MAFComp to get your fuel trims in line...
Use 950cc. When FIC selects a matched set of injectors, they could be using Delphi 1000cc injectors that actually flow less than 1000cc. No injector flows exactly what it's rated at. That's why you want a matched set. FIC could also be using that same Delphi 1000cc injector in a matched set of...
I just took a quick look a your cruise log in Post #50. I noticed a couple of things that stood out. During the first 15 seconds of the log, you're at idle but your Front O2 is not ramping up and down and is reading a constant 0.04 volts. This is keeping you from going into Closed Loop. This a...
It looks like you're on the right track. That idle log looks pretty good. Your fuel trims are good.Don't worry about your ISCPosition bouncing between 28-32. It will change as it tries to adjust idle speed.I'm not really familiar with tuning a GM 3" MAF so I won't comment on your MAFComp...
OK, that log looks good, at least for your TPS and idle switch.You've got a TPS DTC now. You probably caused this if you unplugged the TPS with the key on. Clear that code on the DTC's tab and see if it comes back.Let the engine fully warm up (at least 190*F) before you try to adjust your...
You want the TPSVolts to read 0.63 volts at idle, not 0.9 volts.Start a log with the key on/engine off. Floor the gas pedal a couple of times during this log. Loosen the two bolts that hold the TPS. Turn the TPS until TPSVolts read 0.63 and retighten the bolts. The TPS reading will frequently...
