idk jb4 that well, but ive seen a few logs like that, i was under the impression it just read 100 when not in useMeth signal is pegged at 100% though. Avg_ign ~6 whole run so all the timing advance is getting pulled. Something wrong with meth system after the flow sensor..
I'm running an older non-progressive JB4/FSB/meth system and when I didn't run meth or there was a problem with flow it didn't read 100, at least on Map 3 IIRC. Maybe newer ones are different. But that should be signal to the pump/FSB:
" Meth: Methanol flow (0-100%). The meth display shows a voltage conversion of the JB4 0-5v #15 input. Typically this input is connected to a BMS supplied FSB system which is used by the JB4 to control the methanol pump and measure pump pressure and flow. This signal can also be read from a stand alone 0-5V flow sensor such as the one provided by Aquamist. "
As you pointed the IAT's are not budging at all (should drop a lot) and timing is way retarded. I'd check all the fittings/nozzles and bleed system if it were my car.
I have a question about the 17T and forgive me if it is stupid
is there an interest, an advantage to buy 17t 11 blades?
so in practical terms it all depends on what I'm looking for, it's probably a decision to make with my tuner according to my objectives
"At the end of the day they are shoving big ass 19T wheels in tiny ass compressor housing made for 10T wheels."
Incorrect assumption. They're not hybrid they are bigger turbos. They don't use stock frames.
I don't think any of the hybrids are using stock compressor housings, since they all have 2" inlet and outlets. Even my mmps have a full 19t compressor housing.The turbine housing, yes, they are typically stock (og mmp and pure), or slightly smaller (Franks and most other China), or too much bigger (mmp 1k). The rb gfs are probably the best sized turbine housings.
The only twins is recommend now are frankenturbo (basically Chinas but td04 chra and includes outlets for very close to China eBay price) or RB GFs. The smaller gfs have made 700 (I think close or at limit) and the larger ones have done 680 not maxed out.
Thanks for sharing your experience, throughout, and providing real information along the way. Unfortunately you are not the first person from whom I've heard such a story with ispeedytech.Final update on my early buyer 19T turbo adventure;
Obviously subjective, but my read I would not characterise this as "a bit unlucky".All in all I think I was just a bit unlucky and shouldn't have been a first buyer.
