not having a coolant reading is a big issue. Coolant temp reading negative values kicks in a heavy fuel multiplier as the ecu thinks the motor isn't warm enough to 1) properly seal and 2) correctly...

non oem throttle could be a problem. The throttle pedal module and throttle body are more or less paired units. Typical of of a missmatch to have a p2119 and throttle pedal range code as well to...

Correct, thats a no on the videos.

Well you avoided my rookie mistake from a few years ago. Thats good. ERT is usually well below the start threshold. 07GTS is right, should be 1s, above 300-400 rpm with a 8V or higher IGNV. I...

how did you disable the MAF?
If you just unplugged it you can't do that without rewiring in another IAT circuit back through the MAF harness. The built in IAT on the 5 wire MAF has a huge impact on...

When I dabled in VVE for a short time, I experience the same effects that Chris of HPTuners experienced. Small values 2-15 really not too much to report, no gain in output performance and no added...

SOI shouldnt be adjusted unless your running back to back pulls and verifying the effects. Its probably best you returned it closer to stock.
Really should be validating the SOI with a steady state...

Well need you to provide some background to this request.

1) What are you working with? (Engine, ECU, upgrades)
2) Are you asking us why the SCIAP or TCIAP is not reporting in the software or...

Everything is getting more expensive and time is still time so i feel ya. If you have patience, the guys here are pretty good with the latest Virtual VE (VVE) ecu's.
I started out learning on here...

SES stands for "Service Engine Soon". Selecting this makes the check engine light inthe dash come on when a code is thrown. Deselcting it means the light wont come on even if the code is thrown, so...

Typical pressure test pressurizes air from the turbo to the throttle body by inserting a plug into the charge pipe at the throttle body connection.
Pressure testing the manifold isn't common...

If you really know what your doing then you dont need the kit sensors. I believe the kit bumps the boost to 18-19 psi and the stock 2.5 bar sensors stop at 22.5 psi (255 kpa). To know you haven't...

If its for the 2.0 Turbo SS model (LNF engine) then yes they did. All other options, no.
If you have the 2.0 LNF SS model you will need the 3 bar sensors to go with the flash. There are repository...

There is a stock stage 2 file in the repository which you should be able to access via your HPTuners.com account. These stage 2 files come with 42lbhr injectors stock.

44 lbhr oem injectors rated at 43 psi flow roughly 51 lbhr at 60 psi... so depending on the injector calibration pressure vs. the pressure running now, that is possible. I haven''t tested any ecotec...

Returnless or not, the key is that its a vacuum referenced regulator. It should have a 1:1 reference so its pressure increases by 1 psi for every psi the regulator see's on teh vacuum line. These...

That's what I'm saying.
If you add 5% and the trims report back -4.5% then you IFR value is high by about 8-10%. On the other side if it reports -5.5% then your IFR value is low by 8-10%.
If you...

You should always check the installed sensor calibration data so you know the range. Assess the ECM values to verify the scale the ECM is using. Not all applications ask for the same scale value, but...

some ecu's have sensor calibrations where the map sensor linear rate is reported in kpa/volt and others kpa/5volt. You need to look at the ecu model and verify which one you have. There should be a...

tune the maf in and then add 5+ fuel to the whole maf. If you record rich by 5% after the change then the inject flow rate is pretty close. If not, then you need to tweak IFR rates until it lines up....

i've killed a few that did that. I filled one with soot doing rich condition deceleration tuning. Glad its not an ecu.

so if the mV of the sensor is at 0...did you confirm the sensor is not failed and the signal is in fact being returned to the ecu?
Seems to me like you have more testing to do before you slap an ecu...

Hey dracer! Congratulations on your win! Glad you got something out of the videos before they dissapeared.

Sorry, wish things were different. Even though I don't have a ton of free time to assist, I do think about all of you in this forum quite a bit. I enjoy reading the progress and hearing about all...

base data is the majority of the issues we see. People get take bad data because it runs ok and wonder why it doesnt behave how they predict, or they dont understand the data or system operation and...
