Progress .

Pictures?

Datalog👈
surging non-existent at startup
map is still high 🤡
RPM constant when spraying brake cleaner on manifold and TB🤷‍♂️
Almost feeling brave enough to limp it over to my friends garage a couple blocks over so i can put an exhaust back on it🤠

 

[MEAT]

I should also mention that i found my coil plug wires were mysteriously wired backwards
well 1&2 matched
and 3&4 matched
not sure if that matters or not but they all match now

took out 5% cranking fuel, it lives.

Actually you have setup'd the RDX injectors in the calibration you supplied below. I didn't read you have those. You need exactly the rated flow and dead times.

Datalog👈

It was a calibration, not a datalog. Intentionally?

 

[MEAT]

MAYBE

When putting in injector size, I had chose 410cc & RDX in the deadtime pull down screen. Are you saying I need to manually adjust the numbers?
I believe I've seen the dead times listed on this site before
PS these were purchased off of EBay

 

[LotusElise]

Setup'd idle speed is 750 rpm, MAP should be for that around 280-320 mbar, actually it is on 540 mbar and 1100 rpm and IGT is at 0°, should be around 6°. There is still too much air leakage on the IM side. Torque from combustion is still too high. BTW to high, STFT is actually at -23 %.

Again my question, what is the flow rating and deadtime of YOUR injectors?

We dance in circles here, you have to calm the leakage and to setup the injectors exactly according their specification. Only than you can start tune that calibration.

Thanks for walking me thru this LE

No idea the flow rate of these injectors. Ebay did not send anything other than the hardware. Switch back to stock injectors i guess? even then I dont know the exact flow rate just using the ratings on kpro

This IM leak is killing me, I cant seem to track it down. Idle is not changing when I spray manifold or throttle body.
If anyone needs me Ill be under the hood looking for leaks
TPS just shit the bed too

You can keep them, but the tuning effort increases. If you keep them with the actual setup and before you do any adjustments of the fuel tables, you need to find the MAP feeder. Aim is around 300-350 mbar. Any connection to the IM has to be proven. Also casting errors/cracks at the head side and at the IM itself.

Idle tuning is the biggest challenge in tuning, the rest is easy straight forward doing. So don't be hard on you, just go through all interfaces. Much more experienced race engine tuning guys were challenged by idle tuning with issues like you have with it. So you are still in the normal ballpark of effort. Don't worry, be consequent and detailed, be happy .

Thank You🤙 you're awesome

Side note- Whoever made my manifold neglected to tell me about
the vacuum ports on the underside of my manifold💀
I feel ridiculous but relieved
baby steps

I feel ridiculous but relieved

Whatever it takes, finally you will make it and have learned it .

 

[MEAT]

I think this came from a little trip down the street to weld what's left of my exhaust back on
new

Otherwise it starts right up and idles fairly well.
Completely fell on its face when I applied too much throttle in 2nd

Ill be here learning about fuel trim if anyone needs me

 

[LotusElise]

Better, still too high MAP. It runs still to lean for the idle, which is closed loop corrected by -14 % STFT. Still leakages to find, maybe something bend on the flange side or cracked.

I knew you were gonna say that.
With my hand over the throttle body, the car stalls.
Are you saying the head could possibly be cracked?
Any possibility this is from map placement or manifold type flowing more air than base tune?

EDIT: You have never steered me wrong. I'll be outside lookin for leaks

 

[MEAT]

Ahhh not the head...couldnt think of what a flange was . Kept picturing a gasket

Anywho went out with MAP gas
and tried to find the leak like that. No change
Might go buy a vape pen
Swappped MAP sensor but battery needs a charge wont know til a later today if that makes a difference

Going to inspect the 1 vacuum line I have and the brake booster too

 

[MEAT]

It appears that I don't have a brake booster check valve
I thought it was part of the booster, but its part of the hose.
Its all new hose.

Headed to the junkyard

 

[LotusElise]

It is the very last option to check, but yeah, it is in the range of possibilities. But 1000's of points before to check. I think you are on the right way.

You have never steered me wrong.

Oh, thanks, appreciate you saying this.
