Do you race your car?

 

The reason people aren't seeing problems is because we still have the factory ECU safety features. The sad part is even though the computer is keeping you safe its killing your performance.

A richer mixture with no timing pull and strong advance will be quicker than a lean pull with midrange knock. Timing is what makes good power up top.

 

Yea so people with 20 degrees advance at redline probably feel pretty good.

 

Tuning is more than just AFR and timing. You also have to keep true EGTs in check.
You can slowly kill a motor by runing too lean.

 

There are two schools of thought on the issue of tuning that I have read about so far:

1. This school says that power comes from running as much advance timing as you can w/o knock and not leaning your AFR too much. I think Jeff falls in into this school from his last post to you.

2. There is the second school, that Klaus seems to belong to. He says that best power is produced when the AFR is between 12-13:1 no matter if you have a low compression FI engine or if you have high compression Honda engine. When the mixture is at 12-13:1 and it combusts it gives you the most power, period. So you retard the timing and reduce the boost inorder to hit that number. Basically this school give more weight to the AFR that to timing and boost.

Having looked at the 91 oct off-the-shelf Shiv and my custom map, there is slightly more timing pull in his timing map than my custom 91 oct map. But my custom map is no where near 12.5:1 AFR. My custom map is at 11:1. Check for yorself the attached maps and tell me if you think there is enough timing pull in the off-the-shelf map to allowe 12-12.5:1 AFR.

 

I agree with you Jeff and that is why I want to install an EGT gauge ASAP and I want to log my EGTs with the LM-1.

 

yep i do race it a lot.

 

i dont have an egt gauge but i want to buy it also.
right now i have the oem oil temp gauge.
do you think that the engine oil temp is related or can be related to the egt's of an engine??
cause when i have raced and have really pushed my car it has gone as high as 110 degrees celsius and this has been on a very hot day but most of the time ive seen no more then 90 degrees celsius.

 

ZEITRONIX far outpaces the Innobreak products by far. Their 74 samples per second sampling rate PER ITEM LOGGED is amongst the fastest available. It also logs RPM, LAMBDA, TPS, AFR and AUX1 out of the box without the need to purchase other add on boxes, weighs a few ounces vs. 6.4lbs LM1, includes free datalogging software, logs up to 9 hours of data and is PALM PDA compatible. What more could you ask for?

It was engineered by a DSM road racer. Support the 4g63 brotherhood.

Runs circles around the Innovate units and costs MUCH LESS than the innobreak.

 

Wow! Quite the pitch that was. FWIW, the Zeitronix we tested had a great deal of fluctuation on the AN output. Maybe it was a bad unit, but that was in-line with what he had heard about the Zeitronix. That is why we decided on the more expensive innovate.

 

Just so you guys know, I posted a few days ago how I run 91 at the track with no issues and have done for a couple of years now with my Stage 1+ EVO. Well today I was running at Pueblo and it a 100 degrees and I was running straight 91 and after a half a lap or so my car started pulling timing. It would happen when the temp gauge would start to climb. It was so hot that I could only do one flying lap at a time before the temp would shoot to near the red and it was as I mentioned pulling timing for the second half of the lap. There was no race fuel available and the cause was not the fuel it was the very high intake air temps and my hot hot engine.

I ran the car all day like this with no issues other than slow lap times (we were collecting suspension data so we didn't really care). As soon as I was driving home the temps dropped due to a thunderstorm and I was instantly back to full power. The car is as strong as ever. The point there is that the fail-safes work and no harm done just sucky lap times

It's the first time I had that happen and the first time I've run the car in that hot a weather. The fix is simply better cooling (intercooling and engine) or just stay home when it's really too hot to run at the track

 

What more would I expect from the Vishu forums? I wouldn't feel at home without a zero feedback heckler in the audience.

I will find the article from Import Tuner magazine where it was compared to some of the leading wideband products in a comparison and shined against the Innovate.

Where is your 128mph stock turbo Innovate equipped Vishnu car BTW, I don't see anything in your sig.

 

Come on man lets not take this off topic. There are plenty of Innovate vs Zeitronix threads you can voice your opinion in.

Chronohunter.....are you on a custom tune or standard map?

 

You are very brave.


Also, what about upgrading the fuel pump ?

custom tune on all standard Vishnu stuff, I'm at altitude so the "off the shelf maps" are for you flatlanders
