Sounds like a harness issue.

 

I checked Ultimate A, B, and C connectors against color codes in manual and seems they're wired correctly, not sure on B, C, D connectors that plugged-in into ECU since they all yellow.

Another thing I found that VQ guys now getting the crank angle signal fine, so maybe shop will figure out for my J-series too. Keep my fingers crossed.

 

Good luck Serge!

 

damn, well with any new thing, everything isn't going to work correctly right off the bat, I just hope that you can get it all working with relatively few problems, and little work.

 

Damn, now I'm getting worried. I wonder how my ECU will adjust to the odyssey crankshaft and RL pistons??? Think my ECU will manage the engine a little better than his accord's ECU? If it doesn't, guess I'll be going through the same dilema as serge

So, any word from Kwai on how they're doing with the ultimate? Could you let me know how many hours it takes them to tune? I may be going down that same road. The garage told me they charge $85/hr. for tuning.

 

Your ECU will need no special adjustment because of the new internals. The idle-relearn procedure should be run when you first start the car because the battery has been disconnected for so long. Well, I'm assuming they disconnected it.

 

Serious? Sweet! Yes it was disconnected, but now is reconnected as it has been towed to my house. I will be disconnecting is tomorrow just so my battery doesn't die.

thanks Steve

 

I just wanna know what the progress is with this deal. If the ignition advance doesn't work, then I may just be getting the VAFC or regular e-manage.

 

Why waste your money on the VAFC or the blue e-manage? Neither will give you gains on a N/A setup.

 

sure they will. been dyno proven to gain approx 10-20 whp after tuning.

 

stupid edit time limit.

keep in mind that's his second tuning with the VAFC, so the gains weren't as great. Plus I'll be getting CLS cams, and have a turbo planned for the future, so I'll need some sort of tuning system for it.

 

10-20whp I didn't see 10-20whp in that link. And that was with cams. Kinda hard to tell how much he gained just from the VAFC. Testing was done on a CL-S with the e-manage and no noticable gains were achieved.

 

like I said that was his second time tuning, so the gains were minimal compared to what it would have been right off teh bat. I'm just waiting on the machine shop to finish machining my cams and ship them to me, so I'll be needing some tuning no matter what.

as I recall he gained about 7whp the last time he tuned it, but I couldn't find th edamn thread, so 7+7 = ~14 whp gain.

 

Maybe he gained something however I agree with Steve. I really don't see the point of it on an NA car personally. That 300 or 400 could be spent on something else.

 

not when you ahve every bolt on possible.. I dunno. I just hope this works out.

 

I have every bolt on possible along with some extra stuff and also including nitrous or I did previously on my TL I should say but never saw the purpose of adding the vafc. Anyway, good luck!

 

Yes, I need one

 

As far as EU, my tuner hooked it up and got pretty much the same results with failed TPS calibration until fired up the car, rough idle. However, most important - ignition errors popped up displaying all channels from CH1 through CH6 . The main unit's jumper setting were checked and they looked fine, however now he's got homework to do to check every single harness wire. As I mentioned before, all EU 3 connectors seems have the correct color wires as specified in manual, however all yellow wires leading from ECU (B,C,D connectors) to EU need to be checked to determine if they're trigger the ignition errors and fix where needed.

So, picked up the car last Friday and going to bring it back once harness completely checked. I should find out the results this Friday/Saturday.

 

BTW rtatsutani, E-Manage was determined to be beneficial to FI J-series vehicles, thus you don't need it and VAFC is a waste. In fact, looks like nothing benefits NA CL-S and if I get the desired EU results along with intercepting crank angle signal, then NA benefits will be realized for all types of J-series vehicles. At this point, you should be fine running on stock ECU with your upcoming 3.5L swap.

 

just so you know i have the Uni Chip with only good results...i gained 1.5 MPH in the 1/8th in 10* hotter weather ...the only thing i dont like about it is it's not end user adjustable or that it cant data log

 

Seems Unichip wasn't very promising to majority of NA J32A2 vehicles, while yours might be an individual case. NA AV6 reported some good gains with custom tuned ($200-300) 91+ octane map.

 

^^^ which is why I'm hoping so much that this will work out, because getting the unichip and tuning would cost almost identical pricing to getting the EU and harness with end - user tunability. If this doens't work out then I will .

I know you asked and steve said it didn't really matter(maybe it chages things you can't see), but is the engine parameter set to J30a or J35a?

 

Doesn't matter. J-series is J-series. The parameters within the unit don't change much. At least no more than they would from a J32 on the east coast to a J32 on the west coast. Very minimal differences in settings (given same mods i.e., S/C)

 

well, the engine itself doesn't change much, butperhaps there is a difference with how teh EU intercepts/delivers teh signals, or how it translates teh signals it gets to what it can read. I'm sure teh ECU's aren't exactly the same between teh two engines, so perhaps there is a difference that isn't visually noticeable. I can't find the manual for it, so maybe it is just he basic settings, but maybe not?

 

Nothing changes (except engine size) when selecting Engine Code under Paratemeter Settings. So J30 would read 3000 and J35 3500, the rest remain the same. You can select RPM Signal Type delivery with a choice of RPM signal or Crank angle signal, however it would read from your stock or whatever J-series ECU used as long as harness wired correctly.

 

ok, just throwing that out there. Well something somewhere has to be wrong. It can't be the EU itself, because the blue unit seems to work fine with the J32's.

lEt usknow as soon as it's idling fine.

 

so if i am understanding correctly there really is no benefit to NA j series ? i am installing i/h/e tomorrow and am wondering about tuning since i have read numerous times there is no benefit to the VAFC in my situation so does that also apply to the EU. i would like to tune my engine to it's highest potential

 

sorry it's late and i f@#$ed up the last post and waited too long to edit it, there looks to BE benefits to NA so am i correct in thinking the EU will draw out hidden potential after my mods?

 

there is no proff that it will work yet. serge (02AV6) is testing it out on his J32/J35 hybrid with the J30 ECU, and only if the ignition advance works will it yeild any results for NA applications.

 

And he will not be testing ignition advance.

 

I'm not? Interesting.

The whole purpose of EU for me in the first place was to advance timing over regular E-Manage, getting vehicle speed and tune it with specific parameters, ability to play with rev limiter and a/t shift along with reading IAT/ECT signals. Therefore, until harness is checked/fixed to utilize ignition advance, it's all speculation, however the intention remains to advance timing based on crank angle signal which can be beneficial (assuming success) for both FI and NA J-series vehicles.

 

That was the whole point in the first place of getting the EU over the blue unit. When did you start smoking the reefer steve?

 

You're going to boost 9+psi AND timing advance?

 

For a N/A car yes. But in my opinion the tuning capabilities of the EU over the blue unit are what sells me on it. Boost + timing advance on these motors?

 

haha, that's what I said at first steve, but aparently the timing on the J30 is very conservatve compared to the J32 engines. He said he was gonna try it just on the low end rpms where it needs the power the most.

 

I don't see you following this and other EU thread where I stated needed advanced timing before 3500rpm. BTW, I typically retard timing when approaching redline. And I should see no more than 7-7.5psi with close to 11:1 CR.

 

Ok, so what's the status. Things taking longer than expected?

 

I doubt it dude. I'm sure he'll tell us once there is some definite news... good or bad.

 

I'm out of town until the 5th, so final results next week.

 

this is a preemptive bump for the results, since technically "next week" ends tommorow.

you can tell I'm eager to hear what they are.
