Been a while since i had found time to work on the car, between weather and never seems to be enough time in the day. Wideband is reinstalled, still wired to EGR position input. Readings seem to...
Finally got around to getting a log up in the higher RPM ranges, i had my histogram set up for 25 hits per cell, should i still stick to this even at higher RPMs, what is the lowest i would want to...
You should have battery voltage on the two heater wires for O2 sensor with key on, recommend test light over a volt meter as it will put a load on the circuit, you might see 12v with a meter but it...
Ah yes, almost forgot about that! Did not get a chance to reinstall the wideband, but things are looking much better running both narrowband sensors. No changers were made after log 24, current tune...
Looks like you are having issues with your bank 1 o2, dropping in and out of closed loop, and very little voltage change on that sensor, also will need to confirm proper fuel pressure at fuel rail.
I'm relatively new to this but just taking a quick look that tune looks like a disaster. Also appears there could be mechanical issues, or it could have to do with the displacement configured wrong,...
I will take the wideband out of driverside header and install narrowband, similar to factory location, then I'll weld a bung in for the wideband further downstream, no particular guidelines I know of...
Two logs, same driving route, only change made was the injector select, all 0s vs all 1s. The trim that was way off switched banks, and seems to have switched directions as well, so not sure what is...
Been a few days since i had worked on it, ported out IAC passage, this aftermarket throttlebody is known for issues with very small IAC passages, made some minor adjustments to idle airflow, lowered...
Running dual fans in the series/parallel configuration, i am not sure why i have the temperatures are set so high, might have been something i forgot to transfer over when i switched to hptuners, i...
Oh yeah duh, i wasn't thinking, i did know that. Still thinking ahead, at what point should i be reenabling the MAF?
Doesn't think i have hit PE on any of my drives yet, haven't gotten to that point yet, do fuel trims need to be omitted if the PCM is commanding anything other than lambda 1?
Couldn't get on it too hard, too much rain, but running great for sure! Got another short log here, doesnt look like any changes need made, ill get a better one once weather clears up. I find in...
Is there a limit to how many channels before i start having issues? i have alot being logged. I had injector pulse in before, not sure why i took it off the channel list, but it is added back,...
I have not been clearing LTFTs after each update, i will be sure to start doing that, i thought they would have adjusted automatically? or is it just faster to clear them each time, that way its a...
I havent heard of EOIT before, briefly searching it, it looks like it is the fuel injector timing essentially? Noticing huge improvements! Just got a short drive in today, log attached. Greatly...
They dont appear to be bosch injectors, they say Denso 25326903, i had a set of 32lb knockoff bosch injectors in it originally but decided to switch to an OEM set when i was having issues getting it...
Which part number are you looking for?
Forgot to add, return less fuel rails, using the corvette filter/regulator, and can confirm 58psi at fuel rails at idle, haven't checked under load
Need to disregard long term bank 2 i think, set up now for single bank fueling as talked about above, i do however need to correct my logger setup because the trims on bank 2 will be throwing it all...
Getting much better! Added some extra idle air and it seems to have solved the stalling issue. Every now and then i'm getting some minor hesitation in spots, but i think that should work itself out,...
Can I use the short term and long term idle trims to get the IAC set up properly just like the fuel trims? And what are we looking for in fuel trims? Less than 5% adjustment?
Forced induction might be a possibility in the future, I'm not sure yet, I made the wiring changes on the sensor side of the connector so it would be easy to revert back to factory, I think I will...
So this might be the issue that i should have mentioned sooner, i am currently running one o2 sensor on passenger side bank, wideband is installed on driver side header, I have the narrowband wired...
