Did you check the muffler bearings? Also, last time i was in your car; there was definitely a loose nut behind the steering wheel...

Haven't updated for a while not that I've really done much to it lately but did take it out to SMSP South Circuit again and managed to knock off another second off my lap time with a 1:08.26.

i got the instruction manual for the wideband i want to make sure it's going to be useful before i get it.

"The Bar Graph Display (BGD) Range Setting Mode allows you to fine tune the resolution of this instrument for your specific application. With upper and lower set point adjustability, you can set the BGD to utilize the exact range that the engine / vehicle operates within and see exactly how rich or lean you are running in relation to your current set up and tune. Adjusting your BGD limits also adjusts the scaling of the 0-4v data logger output supplied from the gauge. The selected low set point of the BGD Range becomes the 0v value of the data logger output. The selected high set point of the BGD Range becomes the 4v value of the data logger output. Whenever you change these points, the instrument adjusts the data logger output so that the 0-4v signal is always linear between your chosen set points. "

Looks pretty good Theo. WOT input looks interesting, mine doesn't have that. Although the Innovate's have a built in data logger, whereas the Auto Meter seems to want one connected (which is probably the output you'd use for the F-con).

But at the end of the day it depends on whether the tuner wants to use it constantly, or whether you just use one of those ones you can stick in the tailpipe for the day.

My dyno has its own wideband that logs afr to the graph.

I have 2 standalone widebands that can be used for datalogging or roadtuning.

I recommend putting the wideband in for piece of mind, can then see if u have a lean out etc due to fuel surge or fuel pump failures etc

Howd it go today Theo :)

So all ur worry was a false alarm, the 02 sensor reading in the cypher software the Alex was reading from has no bearing on what the actual AFR's are. Tune was fine except for the 1 area which u heard a ping at low rpm high load which was very difficult to replicate on the dyno due to the auto but i found it and fixed it.

Ps, nice single pegger skid when u left :P

Very interesting today Jez- so we know stock ECU > Theos aftermarket computer> motor.

And I can only read what the stockie puts out.

Had a great run coming back down the old Pac- volvo convoy.

Nice :)

Yeah was very weird, especially how much difference there was in the ignition timing output from his aftermarket ecu to ur software

So second tune and no gains? C'mon Theo, slap a Hypergear in there... :P

All the stock ecu does now Alex is run the throttle and cams, nothing else has a bearing other than to keep the MIL away. I have no idea what signals the Fcon sends back to keep it happy but whatever it is, thank you mr HKS.

Jez also found some little parts of the pre-loaded tune that were no so good - and sorted them out.

I've got some logs from the power runs. Might load them if I can be stuffed

That's why I wouldn't use maps designed for other cars, you will always end up chasing gremlins in the tune imo.

Post them up Alex, I would be interested to learn what the Fcon is doing to the stock ecu and that may hold the key. If I end up going down the Link G4 route I may need the same signal bending output maps... The manual transmission will open up a world of possibilities. ;)

Honestly i wouldnt trust the log files as even the timing etc is way off

Exactly right.

As I said it goes Stock ECU > aftermarket>engine.

So Ign timing is not correct for the engine, but other things like Cams, AFM, and BFS are all able to be seen accurately.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      By Duncan · Posted

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
