Intercooler Install - Before and After...

[Gizmo73]

ok guys - as promised here is the dyno...

the red is my previous run without the intercooler (done a month ago, 08:30 in the morning)

the blue is my run with the intercooler installed... (done last week, 04:30 in the arvo)

There's something not right there. Look where the power drops off up top. The two lines don't line up in either pair.

[Gizmo73]

i think the red lines up with the red, and the blue lines up with the blue...you can tell by using the grid...

However, you are right in that the blue doesnt line up with the red...

As you can also tell, its the stock ECU with speed limiter - cant wait to get that powerfc in to that fix low and mid range 12.5 13 AFR !!

anyone, anyone- Bueller, Bueller....

That's a pretty graph

[Gizmo73]

Thanks Ben - glad you like it.. :nowigetit

A/F ratio's look pretty good. They usaual go into the 11's and 10's with high boost and standard ecu....

[Gizmo73]

yea i know - not bad for a stock 93 ECU, huh ??.....

yea i know - not bad for a stock 93 ECU, huh ??.....

Bloody miracle I'd say.

I have never seen a standard R33 ECU produce A/F ratios anywhere near that good. Ignoring the speed limiter, are you sure it's a standard ECU?

[Gizmo73]

im pretty sure it is - however, you have me doubting now SydneyKid..

Ill check tomorrow, as luck would have it its going in for a service at Just Jap....

If that's a stock ECU then I'll be very surprised too. I've also got a 93 ECU and when I had the exact same mods with 1 Bar of boost my AF ratios dipped into the 9s at one point and were generally in the 10s.

There's no chance your dyno operator could have changed the software on the dyno? It is shootout mode though, so this shouldn't affect it.

[knore]

hes running stock boost i think?

if he is, there is no way that cars making 200rwkw+

theres something wrong with the dyno

[dojobi]

Usually when you've done the intake, exhaust and intercooler mods, I've found that your boost goes up enough on its own to upset the ECU.

[Gizmo73]

stock ecu, stock boost...

Knore - i wasnt claiming the dyno figure as i know this is way too high - rather the difference between the two readings...

Based on the AFR's they mustve got confused with either another car reading, or its some kind of mistake..

ill be getting a real boost gauge done soon - ill also get another dyno run and check out the AFR's and see if there is any difference..

otherwise, ive just wasted my cash on a powerfc !! :jk:
