Yeah, and I don't make any $$$ on this either

Just for the love of the game!

 

Just curious, as if this product/device has the potential to
F*&K-up the engine or anything else? Surprised no one else asked this question.

That's a bit ghetto-style but it does a similar job to what my chip does. Why larger injectors if you're leaning out the car? These injectors put enough gas in the car to support a dry NOS kit.

 

That dyno sheet is showing it running a little rich, 'eh?

SR

 

red line is after tuning and 13.3:1 is not rich. it's safe at level and car made most power. blue line is factory setting and A/F was set at 12:1. 12:1 is very rich for NA cars.

 

MadMax...how is this unit different from your ECU? What would I get with WeaponR for the $500 extra bucks I pay?

 

?

 

Instead of running it at one setting through the RPM range it has its own map that it follows. The dyno tune on mine does 2 things- because it was done with a tailpipe sniffer I know the car isn't running dangerously lean. Also, the computer in it compensates for ECU compensation so it doesn't go lame after a while and require resetting.

 

ad1 is piggy back unit uses air flow signal to change factory fuel map. there are some differences between ad1 and full ecu upgrade. in full ecu upgraded map is set. this works but you do not get the adjustability of ad1.
yes, you can make ad1 stick to your factory map and you do not have to reset it later.
ad1's air/fuel graph shows that car is not leaning at any point. air/fuel graph doesn't get much better then this with this much of rwhp gains.
both system will work but price of ad1 is much less and you do not get much or any more hp with more expensive units.

 

It dosn't show the A/F below 3800 RPM.. that's 2/3 of the rev range.. the setting is fine for the higher rpms but it needs to change for the lower range and I wouldn't buy it unless I saw that it did, which I don't think it does. I like my car reliable, but that's just me.

 

anything under 3800rpm is set at fatory level or little bit richer and i don't think car is leaning from factory. looking at the graph you can see that car is not leaning under full load and that's what it's most important. if you know what i mean. you should know this if you know how to map any stand alones.

 

i have just installed one unit in sc400. it works great. i'll be taking this car to dyno soon. i'll also be tuning turbo charged sc300. this sc should be making over 700+rwhp.

 

It being an LS400 with auto tranny you wouldn't be able to see the full throttle dyno below around 3800 rpms, otherwise the tranny would kick down...

Air-fuel on the Lexus V8s is always on the lean side at part throttle and low rpm for emmissions, economy and to keep carbon deposits down. The plots at or above 15:1 don't bother me at all.

To me, the advantage of an adjustable unit over a fixed ECU is that you could potentially run more advanced timing and it would be easy to adjust the fuel ratios to suit the fuel grades being used. You could also compensate better for future upgrades like intake, exhaust, cams, etc. If its fixed, you've got it optimized for one particular configuration only.

 

i sold few of them and they all works great. i have few in stock.

It's reprogrammable - and the dyno runs I've done have been with the car in 2 and they seem accurate compared to whatever else I see. If I had to choose again I'd stick with the reprogrammable, I feel safer with it since I know what it does at all ranges, and the effects.
