It's disconcerting to read this, I have the FX400X.I'm still having issues getting the tune straight. my tuner has been patient but it's kind of out of his hands. we're sitting at 600/600 and it's drivable, but we can't push the ethanol higher than E52. If you go by Spool's published info on my setup, I should easily be able to push straight Ethanol at my power levels. I'm having issues getting Spool to respond (see final thoughts at bottom for more on this). Sameh is my tuner, so when he says he's pushing it as hard as he can given the tables he's received from Spool, I'm inclined to believe him.
It took 18 dyno runs to initially dial it in... that's absurd. Once we started street tuning, that's where the underlining issues really started popping up, trims getting wacky, throttle closures, etc. Spool has since provided Sameh and Pro Tuning Freaks with the "correct" tables for my setup, that was a couple weeks ago. I've had 2 revisions since then and it's marginally better. Sameh did send over another revision yesterday, that I'll be testing today. Even if it "works", it's still a bandaid because I'm not even close to Spool's claimed flow/output. Meaning, I'm sitting here with a top mount and there's zero chance my setup (in this configuration) will be able to push it to the max or even close.
I've asked Spool for help, and willing to provide them all the logs they want, but I feel I'm getting ghosted. In all fairness, the first time I reached out to Spool, they were all over it. Sent updated tables to Sam/PTF that day. Sameh confirmed he received them and that PTF updated their tuning platform to include these tables. As stated above, it got marginally better.
As far as drivability, feels like stock. The problem is I'm only getting, imo, 10-15% more flow than the stock hpfp/injectors.
Another thing that could be messing this up, but still doesn't fully explain everything, is Spool can't (or won't) tell me which injectors they shipped me. There's a reason lol. I originally ordered the FX-350 and Injectors. After I placed my order, but before receiving anything, they released their FX-400x hpfp and Stage 2 injectors. I contacted them, letting them know I wanted the FX-400x. They asked me to return the FX-350, which I did. Somewhere in there I mentioned it would be nice to get the Stage 2 injectors. When I finally received the FX-400x and Injectors, I assumed they upgraded the injectors to stage 2. I didn't get any up close photos of the injectors prior to the install. I've asked Spool a couple times now which injectors they shipped me, no response. So, Sameh's tune, to my knowledge, is based off me having Stage 2 injectors, but I'm not sure of that.
At this point, i don't know if it's a injector mismatch or Sam/PTF have the wrong tables. I'm really at a loss here. If I don't hear from them by the end of the weekend, I'm just going to pull an injector and get the QR code off of it. At least I'll know which injectors I have.
I fully understood I was getting an unproven product. I just thought Spool would provided more support. Probably would if I had a huge IG account or was a "somebody" in the racing scene.
I want to be clear about the above. Sameh hasn't said one negative thing about my setup or Spool. Spool also did try to reach out to me last weekend, on Easter, but I wasn't able to take the call. I feel I've been ignored since... or they're just really fucking busy.
@razorlab @EddieNel update for you guys... nothing really new. I'll be taking it out later today to test the latest tune revision.
