Limiters off ECU very conservative 295rwhp RB20

[bbenny]

Well i finally got a pre-tuned chip from Toshi, basically had the fuel/boost limiter and speed limiter removed.

Here are the results, i kept things pretty tame with only 10deg advanced base timing with adj pulleys set at 2deg advanced inlet and 3deg retard on exhaust.

I think i really need to invest in a PFC to straighten out my A/F ratio and get a better power curve.

let me know what you think.

Ben.

nice!

well done, have the gears made a good difference in power?

Hey bbenny nice results dude! Just wondering was timing set to 10AD because of the cam gears or because your running a fair bit of boost?

Good work!

[neil_se]

Good result. That's with hks2530 and stock injectors isn't it? I'll be looking at a similar figure soon hopefully.

[bbenny]

I set the ign timing really low for two reasons.

1. i have a shit timing light i cant really trust, and didnt have time to get it sorted before the dyno.

2. i wanted it to be super conservative because i plan on taking it to WSID a few times.

I will hit the dyno again and try smooth out the midrange A/F ratio with the SAFC and maybe give it a tad more timing, just so it creeps over the magical 300rwhp mark

I didnt get to play with my adj pulleys unfortunately. just on the setting i listed above, so i dont know the exact difference they made.

These were on my stock injectors with 2530, the first pretuned chip with high fuel pressure saw the A/F ratio up top below 10! so they can flow a fair bit.

looking good bbenny much better than b4 nice power figure.

Well done Ben, its 20rwhp more than I got on the same dyno with the same 2530 turbo on my R33 during my powerFC tune a couple of months ago.

I bet the car feels quite quick?

[bbenny]

yeah its a bloody rocket! i love it, it pulls harder than alot of GTR's i have driven so im very pleased

i wonder what time ill get at WSID. i really want to get into the 12's but i think i might be dreaming a little on street tyres.

but i have some soft suspension that should help.

Hi bbenny

My chip is not only fuel/boost limiter and speed limiter removed.

Its changed

HIGT octane Fuel map.

HIGT octane Ignition time map

Fuel/Ignition timing TP scale

Some cars TTP MAX

Remove speed Rev Boost Limit

With about 4000rpm the increase is 50hp thsn std ECU.

Top end about 30HP increse.

This chip is basically for all R32 mods 044 fuel pump amd GT2530 turbo .

Price only $200 inc mods ECU and chip.

If I go to dyno with you I be able to make better map for your car .

Please give me e-mail

[bbenny]

yeah definantly worth buying one! cheapest power gain i have ever seen.

toshi was very helpful aand reliable.

[MRK25T]

Ben, do you mind if I get Procar to overlay your 295.7rwhp with a possible future dyno run of my car (since about the only difference between our two cars is yours is a R32 and mine a R33).

My car doesnt seem to want to sell so I may have to keep it.

[bbenny]

the difference is also yours is 2.5L and mine is only 2L i think the engine characteristics are fairly different, but i would like to see an overlay.

[R31 POWER]

Wikked power increase bbenny,I hope when mine is tunned it ends up with something like yours.

[bbenny]

Im sure yours should be sweet, you have all the bits on you need.

I need a PFC to straighten out my A/F ratio and should see a better curve, might give a little more timing too just so i can say i have over 300rwhp hehe

[rb20-calais]

i need 300rwhp, i need a tune at a good place!

Grab Toshi and book an hour or two at Unigroup's dyno. You should be able to get a great re-written computer pretty damn cheap.

[rb20-calais]

I got a Wolf 3d V4 and noone in Sydney are REALLY good with them.

Toshi,

You have experience with them? If so I might get a few hours at unigroup and pay you and we can have a play (with the car of course)

Evan

Evan, giv ethe guys at Unigroup a call and see if they will have a play with the Wolf.They have tuned a range of ecus, and when i spoke to them about 6 months ago they hadnt tried the W0lf ver 4, but were confident it woudl be easier/better to setup then Micxrotech

[Ustasa]

We have had a go on 2 wolf’s recently. Not a bad bit of kit once it’s set up right At least they are full 3D in fuel/ignition mapping.

[rb20-calais]

Might give you guys a call when i get back from the snow!
