I just checked the post again. As soon as I get a chance I'll post the tune here.
The truck's all done. Open loop tuning was very easy. Hp tuners is very constant when it comes to fuel values. The truck runs 14.5-15.4 afr on idle and very small load, 13.5-14.5 mid load, 12.5-13.0...
Just a quick update. We changed the fpr, the original one was holding 40 psi. I also disabled STFT and LTFT. Maf disabled, SD tuning only. Truck runs way better, just after a quick flash. The o2...
The car pulls good for about a minute, even after warm up, but then it hesitates. My original intention was to see if anyone had feedback on similar setups. I'll keep on trying different things on...
Yeah, I have tuned other setups, but not hp tuners. I didn't clarify that. But I am new to hp tuners. Its a great program. I do have maf plugged, but disabled. I didn't want to loose the iat reading...
I have tuned many setups on open loop. They run smooth, and afrs are good, not perfect, but good. Like I posted, the truck is a 77, it gets driven summer only. The fact that the truck has a lot of...
I don't want to disable everything the pcm does, if I did, I would say convert it to carburetor. The o2 sensors are not the only thing the pcm controls, it is just one of many things the pcm does.
He wants to have it running the best possible, it doesn't have to be perfect. We don't need to hit 14.7 afr all the time under a low load. That's why he wants to go the open loop route. He doesn't...
The truck belongs to a friend. He bought someone else's project. We thought the swap was done right at first, but noticed little by little that the engine harness is a hack job. One of the o2 sensors...
I want to tune this car open loop only. It's a summer vehicle. It doesn't get driven often. Do I need to have it set close loop for the ecm to run properly? Or does HP Tuners not work open loop only?
Hi, I'm new to HP Tuners. I'm working on a 77 C10 with a 5.3 swap, trans is a 700R4. Working on adjusting the trans cable, but in the mean time, I can do 1 pull on the truck, and after that 1 pull,...
