... Perhaps you should look into the two pins on that connector that drive the MPI relay functions and figure out why the relay chatters. Both of the pins pull...
I would suspect that either the large (SOT-223) transistor on IC110 is bad (shorted) or there is a caps-leakage-caused short on the circuit that runs from...
... Oh, that's what you meant. Hrm... well, it is true that the compression is the same... but the amount of air and fuel is greater, right? Kinda the...
This is interesting. From what I've read, Stroker motors( with a lower rod ratio) generally require more timing advance than a comparable 2.0. This is due the...
... It was hypothetical. ;) I'm just trying to take the static compression out of the mix. But, I guess in reality, the higher compression ratio you end up...
Jeff O., ... Just my $.02, I think there is a bit more to it than just CR. One data point, my ~9.2:1 stroker requires a good bit less timing at high loads...
Just a follow-up on further data analysis using more data: For my 2.3L the ecu-desired ignition timing change with respect to engine load is ~-0.34 degrees /...
... is ... I could not find any SOT-223? COuld you please send me a photo? That would help a LOT. Also what if I just change the IC110(92 eprom turbo ecu) with...
Dave was referring to the formfactor, not the part number, of the bad transistor on IC110. It is the largest transistor on IC110 (three leads plus a heatsink...
... IC 110 is different between pre-91 and post-91 ECUs so you can't just swap the one from a 90 ECU over to the 92 ECU. They are the same between turbo and...
... Thanks Steve. I was responding to Jeff's comment about IC110 and was thinking about the MPI relay driver transistor as you mentioned (and I had just...
I was under the assumption that since I had everything rock solid on the stock 450s (even with the NT FPR), if I set the deadtime and the global inj scale...
is My same question I have a MD193300 Eclipse AWD 1993/AT MH6111E853 Eprom EA02... the code of E931/932... is compatible these code??? tanks Rodrigo ... run an...
Shawn, I've never seen any reason to use progressive deadtime. If you plot most deadtime curves, they all seem to be rather parallel. Plus, your ECU actually...
I started out with that progressive code but that adds 8us at 14v, it goes to 9us at 11.68v. With that deadtime the High trim was offscale rich (81%), Mid and...
... close to ... then adjust ... That sounds like a good plan. I usually adjust the Global Fuel and/or the AFPR to get the HIGH TRIM close, and use the...
I just checked the part # and they are indeed ND660s however I've read quite a few people have had their ND660s checked and they vary from 640cc up to 720cc so...
Hi: I tweaked my spreadsheet some more, and added two parameters that basically act as independent sliders for the low-end and top-end timing increments. I...
Shawn, ... FYI, my Denso 660s tested out at 700cc @ 43psi and I'm using the same deadtime as Jeff O. I'd definitely get them checked, since it will make a big...
Luke, ... Which turbo is this? On a 2.3L + Garrett GT30-11BB turbo I'm hitting rows 7&8 (double range maps) at 8-10psi. That's a huge difference. Kyle...
I'm still playing with it, I'll get it figured out. I'm going to send my injectors in with the group once we set a date. For the MAF comp, turns out I must...
Can anyone confirm this file is a working copy of the 2G EB23e 2nd Gen ECU's code? The file is under '-> Files -> 2G -> EB23E -> eb23e.dis.txt.gz ' Doesn't...
I am running PTE GT32 with the smaller 71mm compressor wheel ( also available with the 76mm compressor wheel, marketed as GT3255 ) Here's the calculated...
Why can't we simply log 0x54 or 0xe3 which is the g/rev value for double-load or single-load code, respectively. Multiply this by rpm, then you can get g/min....
Maybe i'm way off base, but couldn't one, with the correct code, use the rear 02 data of the obd2 to output the knock count in some fashion to a palm logger?...
Ignore my previous data point. It was difficult to pay attention to the displayed load-row while at WOT. So, I updated the logging software to capture min/max...
The other day I was doing some tuning on an Evo I-III N/A Lancer that was converted with a 4G63T and Evo ECU. While logging I realized that the MAF reading ...
