Got my full versions of both tunerstudio and megalogger. However I'm having very bad idling issues, any ideas?

Yeah. Tune the car

Okay, I've got an annoying problem. Car idles fine now, however, whenever any throttle input is applied she dies immediately. Almost seems like she runs way too rich because I can smell fuel whenever that happens. I should also say that the tps isn't screwed on, nor is it even being picked up by the ecu. Can someone help?

screw in the TPS and then connect it to the ECU so your accel enrichments are so royally fucked...

Getting white smoke coming out of the exhaust...

Okay, so car idles fine, however she won't rev past 2k and will protest every second of doing so. I'm trying to attach my data log of doing this but can't find where to attach it. Help?

Click the paperclip.

Okay, file should be attached. Thanks! Could the timing be off at all? Also I bolted down my tps and I'm still getting no response through the ecu, nor is the ecu reading the correct afr. Saying 7.8 at idle and when the car is off.

You need to make your TPS work. Then make your wideband work. Then tune your car.

LittleCarBigFun 05-15-2018 09:02 AM

That's my biggest problem is that I don't know how to tune. I don't know what to look for in any of the graphs or tables. I also don't know how to get my tps or my wideband to connect. I've tried to configure the ecu to the gauge but it does nothing.

concealer404 05-15-2018 09:05 AM

Ok, so the car won't rev past 2k, but your log shows it sitting at 3600 the whole time. Was this idling? Were you driving?

You're in way over your head. Step away from the car for a couple weeks, and don't touch it until you've spent 2 weeks reading.

Gotcha, one my local tuners does Megasquirt so I'm getting him to give me a hand in this stuff. I'll also give the car to him for the month of June since I'll be out of state. Hopefully he'll be able to get her running good. Thanks for the help

I'd fix the mechanical issues you have before you hand it off to him. Most tuners like tuning, not wrenching.

He run's his own shop and does both. He actually does damn good work. And I'm also not sure of any mechanical issues I have at the moment.

Well your TPS and Wideband don't work. And you didn't answer if the car was idling at 3600 or not, so that might be a problem. I'm not convinced i love the kpa values in that log at a steady 3600rpm either.

Basically what i'm saying is that this car is very far from being ready to be tuned.
