Is piggyback good for BOT proejct that exceed 100% of stock horsepower ?
Regard above question . I will say piggyback no longer a right fuel management if power produced after BOT exceed stock power another 100% !! Let say stock 120 - 130 bhp . And you got you ride BOT and boost 1 bar . With that boosted pressure , the rated power should be around 260 - 280 bhp. Is 100% improvement over stock power. My personal opinion, piggyback is good if power make not exceed 50% over stock power. If more than a basic standalone is better than that. I am being tuned more than 10 campro BOT . Majority is xenon's customer ride . Only one BOT campro was using haltech sprint 500. The rest is either haltech interceptor and unichip . The one with haltech sprint 500 is really impressive with response . TD04HL used in this Campro BOT. I can find the difference if compare those campro BOT with TD04HL and use piggyback as fuel management. Overall performance is better !! So my advice is looking for right fuel management if you decided to boost above 0.5 bar . Nowaday basic standalone like haltech sprint 500 & adaptronic e420 is affordable. You just need to spend another RM800 for better performance !! I know is a pain to pour so much at once. But you will even pain upgrade from piggyback to standalone !! Many of them just thinking standalone is too much , i am totally not agree. Standalone is just nice and not too much. When you decided for BOT , you should make a brilliant choice on fuel management.

I have to agree with you on this. If you still remember me, i am the owner of the Silver Waja in PJ. (Xenon's cust). I was advised to go for standalone for better response and less hesitation but due to budget constraint, i made an informed decision to settle down with Interceptor. My max boost now is 0.7 bar and the power is more than sufficient for my daily use. The only problem bothering me is the Siemens ECU "sometimes" go into safe mode (but check engine light did not appear) after boosting. Engine became unresponsive and hesitate to rev. When i restarted my car, everything became ok and i can drive like normal. After consulting Xenon and reading your write up, i can safely assume that the culprit is the piggyback and 0.7 bar boost. By replacing the interceptor with Sprint 500, will it eliminate the safe mode problem and improve the throttle response?
ReplyDeleteI'm facing the same problem. The Siemens went to safe mode..sometimes after boosting..and sometimes without boosting..currently running on 1Bar..Is there any other way to fix this problem rather then changing to standalone? and Is it 100% confirm that changing to standalone will eliminate all this safe mode?
ReplyDeleteKindly advice...thanks
