My new vzr n1 version 2
- Thread starter n15...
- Start date
Have you tried a blanking cover for a sink? Where there are two holes for taps you can get a blank to fill the hole if you have one mixer put in. They're usually polished stainless or chrome and screw in from behind with a gasket so as not o let any water in either. Just an idea. May be worth a trip to homebase with a measuring tape.
Here is what the tuner had to say.... looks like the whole exhaust system is getting the bin...
HI Paul,
I have done some more testing on the car yesterday and this morning. What I have found so far might upset you. The results are as follows and mostly form memory.
Final map made 201 bhp and 170 lbs of torque.
With the back box removed +10 bhp + 5 lbs of torque.
With the exhaust removed form the decat pipe +20 bhp +8 lbs.
Its safe to say that with a properly designed exhaust it would be possible to get 230 bhp and 185-190 lbs of torque form the engine.
I have found that I have saved some of the test data.
This is with the std exhaust all connected.
Estimated Flywheel
Estimated Axel
Back box removed is the red line Axel.
Back box removed is the red line Flywheel.
I dont have the results of the total exhaust removed.

Either this guy knows his stuff & has identified an area for improvement, or he also makes exhausts & wants to rip you off ?
Those graphs (while generally impressive) show one hell of a weak spot between 3-4k rpm ? What is he using to combat that ?

I think this guy knows what he's on about. What exhaust are you running? Checked the specs but couldn't see it. You could get the powerland header modified or sell it and spend more $ on an ASP something. Nice 3" pipe out if the de-cat straight to backbox and a decent can. If it was like a 5hp increase for a decent exhaust then you wouldn't worry but an extra 20 ponies! Got to be worth chasing.
He would be considered an sr and rb specialist over here but as you can imagine it's the first time he has ever had to combat that daughterboard or a vvl powered car, tuning these yokes has never really been done people have fitted bolt on's and have been happy with them mine and patjoes silver one were pretty much the first two.
He doesn't make exhausts just mine is a fuji and only 2 inch so I always knew it would be a restriction just not that much.
I'm afraid its alot got to do with the ecu as to why the map isn't 100 percent he was saying it lacks resolution to tune he was saying that if he got it right at 50 percent throttle that 70 percent would automatically be knocked lean again or vise versa which made him make certain parts of the map very rich... another e-mail which might sound clear that he sent me
Ok I have made good progress mapping the ecu for basic fuel and timing but that's about all. there are too many maps missing for this to ever be a successful solution for getting the most out of the engine. I need to find a better way of accessing all the tables so we can tune the load on the maf with a trim on tsp. Also there is no way of controlling the injection timing which is crucial for tuning high comp NA engines.
This guy is a motec and NIStune dealer. I have to say he made heaps of effort to make the ecu work for the car and worked on it a lot even on the bank holidays and was e-mailing me right up to 11 at night sometimes working out solutions to sort it and i'msure that was hard enough considering he has small kids in the house. He was fairly deflated by the results and also had no explanation for it running out of steam at 7k it makes the power even without that but he wasn't happy none the less he was thinking that cam gears may solve that. I also think that the head isn't shimmed properly it's too tappy for my liking in that area so I may go back and check again, although he never found issue with that. I also think that maybe the monster valves may have shifted the power band back a small bit? becuase with the exhaust off it seems to make the power most others seem to have gotten from there builds just at lower rpms i have never seen a dyno for anyone that had them fitted may be interesting to see patjoes one when its done.
Stage 4 franklins an option maybe. Another issue i'm sure you realise is that I had a compression ratio of over 12.5:1 running on 95 fuel and I made sure going up it was just your regular stuff in it so that it would be driveable every day.
Any feedback on that for me lads i'm all ears.

From what I remember being told, Robbie is very very good at what's he does. Tuned 3 hondas and they all came in. 1st 2nd and 3rd in a race. Can't remember what one.
Are you sure its them?
So these ECUs are just not good enough for a decent map I'm getting a link ecu for mine g4extreme its gonna be expensive but its something I can always bring to another car again

its not actually the ecus that are the real prob damo its lack of development of the address file thats the problem. There not supported by nistune so they wont spend the cash to develop it properly. Anyway if it made 235 out of that ecu with a decent exhaust id be more than happy. I wouldn't get link because it still leaves ya with the distributor which is another weak link. If i was spending the money id want rid of that too.
. Hopefully with the exhaust sorted and cam gears you should get a lot better results. 
@steve He knows this and tuner has said he could get 260 out of engine with standalone but he will get 230 out of daughterboard so its 3k for an extra 30hp! If it was an all out track car like my ae86 ya def but this is his road car too so with those nice torque figures he'll be flying!!
@kilcosdc Exactly, he has made great progress with it and the ECU's are perfect for the standard N1 and VZR engines its just more difficult with Paul's high CR build. Great too have someone in Ireland capable of tuning these at last!

easy to make a crap 4-1 header, interesting to see what the new changes bring. difference i guess between a header and a great header is vast, interesting read mind.

Will be interesting to see if N1 manifold actually makes any diff as this guy can be temper mental! He commented before on my brake setup " Oh I see ya went with the leakwoods....." My WillWood setup on my old silver car!!
Paul I'd say some one will easily be able to sort the merge collector on that mani, maybe even measure the lengths and sort it if there is a mistake
Ill be going coil on plug with the link just need to Fab up a trigger wheel in a old dizzy I have. But that's down the line just wanna get it going for now

i agree 100 percent with ya steve but its a compromise for huge cost as patjoe said. If however i was told that the ecu compromised the safety or reliability of the engine i would have gone with stand alone all day but for what i need its perfect. From day one i was expecting that i wouldn't get full power out of it. The suprize for me was the exhaust and the fact the valves have pushed the power band down which i dont really mind
as long as the power is there the lower down it makes the power the more those wonderful torques i earned will come into play. For me im very happy i have a platform on which i can build on and i know little changes are going to make big improvements in it. A true modifiers car is never finished there are always tweeks and adjustments to be made!

Why a G4 damo compared to others?
Is it the cheapest to run 8 injectors?
If I was going standalone i'd just run 4 big injectors, s15 injectors are 480cc and can be got for less than €150 for 4.
Save alot of time and money imo
I've got an Omex 600 for the ae86
