I plan to use the TDC in the Dizzy for engine phase and the 12-0 in the Dizzy for crank location. I hope it all works out.
On a friend's Civic I'm using CKP+CYP to get full sync signal, so I can get sequential fuel on 4 injectors and drive COP coils. I recommend to use CYP instead of TDC, think is easiest!
Here are a few pics of the 85 CRX with the B18C installed. Next step is to verify ignition timing and then the tuning begins. The motor clears by about 1/4 inch almost everywhere.
Should we go about our build schemes backwards, if you will. As in, socket our ecu, start studying the stock maps, maybe do a little tweaking, all the while closely monitoring A/F and diligently logging data, and after becoming completely comfortable with the process then going on to bigger physical things. (i.e. turbo, cams, forged internals, ect..) And in doing so, is it possible we can just tune our own cars instead of paying 1000$+ dollars for a tune?
Obviously we can't all own dyno's... but every major city has a dyno day where you can get your car on for cheap and make your own adjustments, thus becoming your own tuner.
Yep, I am going about mine backwards - rebuilding engine before trying any engine management. I have zero (0) knowledge of how to tap into my ECU and study what is going on. Hope to learn here.
The 85 CRX is running now with a B18C running a Megasquirt. It started on the second twist of the key. On the first twist, the timing was 360 degrees off. One tweak and it fired right up.

Oil pressure is mechanical. The strut bar has been in the car for 25 years. I have no clue.... It was a street car for only 3 years before it was converted to a EP autocross race car.
I wanted to bring this topic back to the top since I think it could be one of the better threads in here if it stays on topic. I also have a MegaLog Viewer question.
I've been kind of casually using the software for a couple of years now and I've never been able to get the calculated fields to show up in my list of displayable fields at the bottom of the graphing screen. I have tried checking/unchecking, re-filling th erequired parameters, and reloading the log files. Am I missing something?

Can you post your data here and give me an example of what you are trying to calculate? If I can't help, I bet I can get to someone that can help.
Okay, here's an example. I opened up MLV on my spare machine and loaded a log. Selected and filled out the required constants for accel HP and aero drag, let it reload the log. The fields are still not available.Is it possibly a field naming error with my csv file?
Here's a screencap of my csv (NepTune), I'm not sure how to/if I can upload this file type. Let me know if you need the whole thing, I can email it to you.
Got a question. I'm getting my motor back together. I been in contact with allot of tuners and NOT (1) will tune my car locally due to my JDM SIR-G Automatic Transmission. The only tuner that will tune it is Xencron that is 246 miles away about 3.5 to 4 hour drive from me.
The question is will it be safe to drive it up there on a base map that Xencron all ready chipped my JDM P30 ECU on a LS/VTEC with OEM ITR 81.25mm pistons and fully built B16 head with JDM CTR camshaft, RC310cc injectors, etc. I'm also running a AEM oil pressure gauge and AEM wide band. My fuel system been upgraded from the fuel pump all the way up to the FPR/Fuel rails (fuel gauge mounted), Transmission cooler and I'm running a aluminum full size radiator.
It will be tuned on Neptune (Demon 1)
I'm not swapping it to a Manual transmission so PLEASE Don't ask period. I just need to know can I make it to a tuner or I need to make other arrangement like calling a transporter.

If you're n/a and the base map accounts for your injectors, you should be fine. Watch the wideband. If it goes above 15 (n/a) in any sort of heavy load, that's bad. If it stays under 14 you should be fine. I wouldn't go WOT either way but if you do try, keep an eye on the wideband, you wanna see 12.8-13.1 ish (or richer for safety) at wot.
I'D be happy to tune it too, but xenocron is probably closer and would have more experience I'm sure (not knocking myself bUT theyve been at this longer and have surely done more cars).

Thanks for the advice I keep that in mind with the wideband. I think I'm going to attempt the drive.
I know for boosted cars they take off the charge pipe or waste gate springs while driving to the tuner. So I was not sure with N/A. That's why I asked rather be safe then sorry.
Yeah just take it easy on the drive and keep an eye on things and you'll be fine for break in and a drive to the dyno. That being said, you do need to go to wot a few times to break it in before you make that drive. DO NOT make it before you break the engine in, or you'll never get the rings seated properly.

Definitely better safe than sorry, but engines can go pretty lean on light cruise, even FI (as light cruise on fi should still be under 350mbar), I've run mine smoothly to like 17afr (not that I recommend that for anyone who doesn't know what they're doing) at under 350mbar.
Spadam makes a good point if it's a fresh build, if you see above 14.7 at WOT you may have some cause for concern though but you definitely want your rings seated proper
My builder is going to break it in for me then I will drive it back to my state (77.5miles) and then I do the 500 miles oil change and then the 1000 miles oil change after that I will drive it up to the tuner.

Are you sure you'll be able to do 1500 miles without ever going WOT? Hope you don't have to merge much..lol
